WORK AND ENERGY

Front

What happens to the elastic potential energy of a coil spring when it is compressed?

Back

The elastic potential energy increases.

Front

What happens to the total energy of a body falling freely towards the earth?

Back

The total energy remains constant.

Front

When a car accelerates on a level road and attains a velocity 4 times its initial velocity, what happens to its potential energy?

Back

The potential energy does not change.

Front

What type of energy does water stored in a dam possess?

Back

Potential energy.

Front

What is the angle between the force and displacement in the case of negative work?

Back

180°.

Front

Define work in the context of physics.

Back

Work is defined as the product of the force applied to an object and the distance over which that force is applied, in the direction of the force.

Front

What is kinetic energy?

Back

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, such as gravitational potential energy.

Front

Explain the principle of conservation of energy.

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
