What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is commonly associated with the height of an object above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion. It depends on the mass of the object and its velocity.

Front

A car of mass 1000 kg is moving at a speed of 20 m/s. What is its kinetic energy?

Back

Front

What factors does potential energy depend on?

Back

Potential energy depends on height and mass.

Front

What factors does kinetic energy depend on?

Back

Kinetic energy depends on mass and the square of velocity.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as height increases, assuming mass remains constant.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy increases with the square of velocity, meaning if velocity doubles, kinetic energy increases by a factor of four.
