## Collision of bodies

What is called a Collision? Collision is an event in which two moving bodies or one moving body and other stationary body collide (strike) with each other. Collision between two bodies is said to beRead More →

## Kinetic Energy & Power

What is called Energy? Energy of a body is defined as the capacity or ability of doing work. Kinetic energy is most important in among all forms of energies. Energy is measured by the amountRead More →

## Elastic Collision

What is called an Elastic Collision? Collision is an event in which two moving bodies or one moving body and other stationary body collide (strike) with each other. In an elastic collision – Momentum isRead More →

## Conservation of Energy

What is called “Conservation of Energy”? The principle of conservation of mechanical energy states that – If only the conservative forces are acting on a body, then its total mechanical energy remains constant. Total mechanicalRead More →

## Work Energy Theorem

What is called Work? Work is a form of energy. Work is said to be done by a force, if the force applied on a body resulting in the movement of body by some distanceRead More →

## Kepler’s Law

What are Kepler’s Laws of Planetary motion? To explain the motion of planets, Kepler formulated three laws which are popularly known as Kepler’s law of planetary motion. These are – First law of Elliptical orbitsRead More →

## Gravitational Potential

What is called Gravitational Potential? Gravitational potential at a point in the gravitational field of a body is defined as the amount of work done in bringing a body of unit mass from infinity toRead More →

## Acceleration due to Gravity

What is meant by “Acceleration due to Gravity”? Earth attracts all bodies near its surface by a force of gravity called gravitational force. The acceleration produced by this force is called earth’s acceleration due toRead More →

## Gravitational Force

What is Gravitational Force? In universe, all bodies attract to other bodies with a force of attraction called force of gravitation or gravitational force. This force of attraction depends upon the mass of interacting bodies andRead More →
