Peculiarity of an honest Physics Tutor
Peculiarity of an honest Physics Tutor

Have you ever wondered who requires a teacher and at what instance? A large number of people have had bad experiences because regrettably, they received tuition from unsophisticated, ineligible, or non-certified teachers. In any case, if you're trying to find the simplest Physics tuition in your science classes, then you ought to hire a knowledgeable physics tutor.

Looking for an honest physics tutor


First and foremost, that specific tutor must have an in-depth knowledge of the topic. The concerned individual should hold a minimum of a university degree in physics, or during a field that falls within the physical sciences.

Professionally certified

In many instances, parents have the habit of requesting a number of high school graduate students within the neighborhood to assist their kids with studies. However, this is often not always the simplest solution. Always confirm that you simply hire someone who is professionally certified to be a physics teacher. This is often so since they need the proper amount of data that's essential and required to supply the essential support required by the scholars.

Able to apply multiple techniques

A qualified and professional physics teacher must be ready to make use of a spread of techniques. He/she should explain the concept to the concerned student thus entirely clearing any real doubts. This is because many students usually find it difficult to grasp physics properly.

A good physics tutor should have the power to spot the matter that the scholar faces with this subject and in what particular topics and slowly help them out. In most instances, students just become overwhelmed with the tough formulas and ideas of physics.

Make learning fun

One of the qualities that one should need to be a successful physic tutor is that they ought to have the power to form learning fun and enjoyable experience for learners. Make students comfortable to ask questions, this manner they're going to be ready to clear whatever doubts that they might be having.

With friendly behavior, an honest tutor can help the kid begin and ask whatever question he has in his mind. This goes an extended way in helping the scholar overcome his fears and obtain the proper knowledge from the expert resulting in overall improvement.

Engage in practical activities

The ability to interact in several sorts of activities with students to draw their attention to the topic should be a serious trait of an honest physics tutor. He should demonstrate how things function, perform some simple experiments to elucidate the theories, and may also take you on each day trip to the physics museum.

What is motion?

It is defined as displacement or movement of a body or an object from its initial position with respect to time. For example a body A can, be said to be in motion if it moves from point a to b.

Motion is perceived by different laws of physics. Among the laws Newtons laws of motion are studied in classical physics.

Newtons law of motion are categorised in three different laws.

First Law: In an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a net force.

Second Law: In an inertial reference frame, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma.

If the resultant force F acting on a body or an object is not equals to zero, the body will have an acceleration a which is in the same direction as the resultant.

Third Law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.



Newtons law of motion

To understand the law of motion clearly, we need to understand force.

Force: it is defined as a push or pull.

To push an object like closing a door, and to pull an object like opening a door towards oneself.

Application of push or pull may not result in the opening or closing of the door. For some observers lack any motion may be inferred as lack of force but the person applying the force knows that he has put an effort. In clear terms a force is just the application of push or pull or an effort and the results are not required.

Linear motion
Linear motion

Motion in straight line or an irregular path with no angular acceleration can be defined as linear motion.  It is understood as linear motion or any other motion based on an observer and the point of reference entirely.

Circular motion
Circular motion

Circular motion can be defined as the motion of a body or an object on a circular path as shown in th  picture. For a body to be in a circular motion, their is a force which pulls it towards the centre of the circular path. This force is known as the centripetal force. And this force is cancelled out because of the motion of the object with a velocity on the circular path. Which in turn helps maintain the motion of the object on the circular path.

The Solar System


The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. The star system we’re most familiar with, of course, is our own.


Our Home:

If you were to look at a giant picture of space, zoom in on the Milky Way galaxy, and then zoom in again on one of its outer spiral arms, you’d find the solar system. Astronomers believe it formed about 4.5 billion years ago, when a massive interstellar cloud of gas and dust collapsed on itself, giving rise to the star that anchors our solar system—that big ball of warmth known as the sun.

Along with the sun, our cosmic neighbourhood includes the eight major planets. The closest to the sun is Mercury, followed by Venus, Earth, and Mars. These are known as terrestrial planets, because they’re solid and rocky. Beyond the orbit of Mars, you’ll find the main asteroid belt, a region of space rocks left over from the formation of the planets. Next come the much bigger gas giants Jupiter and Saturn, which is known for its large ring systems made of ice, rock, or both. Farther out are the ice giants Uranus and Neptune. Beyond that, a host of smaller icy worlds congregate in an enormous stretch of space called the Kuiper Belt. Perhaps the most famous resident there is Pluto. Once considered the ninth planet, Pluto is now officially classified as a dwarf planet, along with three other objects and Ceres in the asteroid belt.

Gravity (basic)
Gravity (basic)


It is a natural phenomenon by which all things with mass and energy including planets, stars, moons, galaxies etc. are attracted to one another.

We all feel the gravitation of earth as we live on it. It pulls us with a force equal to our weight. Weight of all the physical objects and the atmosphere etc. on earth is because of the gravity. Tides in the ocean are caused because of the gravity of the moon.

Newton’s theory of gravitation

Through time many scientists have theorised about gravity or gravitation and English mathematician Sir Isaac Newton is considered one of the greatest contributor. He in 1687 published Principia which hypothesizes the inverse square law of Universal gravitation. The equation is the following:

Where           F = gravitational force between two objects

           M1, M2 = mass of the two objects

                       R = distance between the two objects

Elements (Metals and Non-metals)

Elements are the fundamental building block of all the matter that we see all around us like the river, rock, earth, the sun, the moon, air, everything else that we can observe.

Elements are grouped as metals or non- metals.

Metals and non-metals are classified according to their physical properties and also their chemical properties and the arrangement of the electrons in the atoms.

The properties of both metal and non- metal are shown below in the table.

Atoms and Molecules
Atoms and Molecules


All matters (solid, liquid, gas, plasma), that we see around us are made up of atoms and molecules.

What are atoms?

Atoms are the fundamental unit of all the elements. It is what gives the physical and chemical properties to metals and nonmetals.

To further break an atom will result in subatomic particles like electrons, protons, and neutrons. Only the combination of these subatomic particles which is stable gives an element its characteristics.

*There are also many theoretical and discovered subatomic particles like bosons and fermions.

There are more than 110 discovered elements (atoms) as shown in the periodic table.

Each atom consists of nucleus and the electrons revolving around it. Protons and neutrons are itself in the nucleus.



     Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and several neutrons. Only the most common variety of hydrogen has no neutrons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively – such atoms are called ions.

The number of protons in the nucleus is the atomic number and it defines to which chemical element the atom belongs. For example, any atom that contains 29 protons is copper. The number of neutrons defines the isotope of the element. Atoms can attach to one or more other atoms by chemical bonds to form chemical compounds such as molecules or crystals. The ability of atoms to associate and dissociate is responsible for most of the physical changes observed in nature. Chemistry is the discipline that studies these changes.

What is a molecule?

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.

A molecule may be homonuclear, that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (two hydrogen atoms and one oxygen atom; H2O). Following figure is representation of water molecule. The red sphere is oxygen atom and the yellow spheres are hydrogen atom, bonded together with covalent bond, thus forming a water molecule.



Molecules as components of matter are common. They also make up most of the oceans and atmosphere. Most organic substances are molecules. The substances of life are molecules, e.g. proteins, the amino acids they are made of, the nucleic acids (DNA & RNA), sugars, carbohydrates, fats, and vitamins. The nutrient minerals ordinarily are not molecules, e.g. iron sulfate.


However, the majority of familiar solid substances on Earth are not made of molecules. These include all of the minerals that make up the substance of the Earth, soil, dirt, sand, clay, pebbles, rocks, boulders, bedrock, the molten interior, and the core of the Earth. All of these contain many chemical bonds, but are not made of identifiable molecules.
