Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv^2

Front

What factors affect gravitational potential energy?

Back

Mass, height above the ground, and gravitational acceleration.

Front

What happens to gravitational potential energy when an object is lifted higher?

Back

It increases.

Front

What is the principle of conservation of mechanical energy?

Back

In a closed system, the total mechanical energy remains constant if only conservative forces are acting.
