How do you calculate the kinetic energy (KE) of an object?

Back

KE = 0.5 * mass * velocity^2.

Back

200 Joules.

Front

What is potential energy (PE)?

Back

The energy stored in an object due to its position or state.

Front

How is gravitational potential energy calculated?

Back

PE = mass * gravity * height.

Front

What factors affect the kinetic energy of an object?

Back

Mass and velocity.
