What is the formula for kinetic energy?

Back

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational or elastic forces.

Front

What is the relationship between work and energy?

Back

Work is defined as the transfer of energy that occurs when a force is applied over a distance. The work done on an object is equal to the change in its energy.

What is the equation for gravitational potential energy?

Back

Front

Explain the concept of power in physics.

What is the formula for spring potential energy?

Back

How do you calculate the braking force required to stop a car?

Front

What is 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.

Front

Define the term 'mechanical energy'.

Back

Mechanical energy is the sum of kinetic energy and potential energy in a system. It is the energy associated with the motion and position of an object.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not.
