kilogram (kg)

Front

What is the formula for calculating kinetic energy (KE)?

Back

KE = 1/2 mv², where m is mass and v is velocity.

decrease

Front

What is gravitational potential energy (GPE)?

Back

The energy an object possesses due to its position in a gravitational field.

Front

At which point does the ball have the greatest gravitational potential energy (GPE)?

Back

At the highest point of its trajectory.

Front

What happens to the GPE of an object as it rises higher in a gravitational field?

Back

It increases.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass.
