What is the definition of kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which depends on its mass and velocity.

How does potential energy change as an object moves up a hill?

Back

As an object moves up a hill, its potential energy increases due to its height above the ground.

Front

How does kinetic energy change as an object rolls down a hill?

Back

As an object rolls down a hill, its kinetic energy increases as it gains speed.

At which point in a pendulum's swing is potential energy the greatest?

Back

Potential energy is greatest at the highest points of the pendulum's swing.

What happens to the total mechanical energy in a closed system involving potential and kinetic energy?

Back

The total mechanical energy remains constant in a closed system, as potential energy converts to kinetic energy and vice versa.

What factors affect the amount of kinetic energy an object has?

Back

Kinetic energy is affected by the object's mass and the square of its velocity (KE = 1/2 mv^2).
