Front

At what point does a thrown ball have the most gravitational potential energy?

Back

At the highest point (X).

Front

According to the Law of Conservation of Energy, if kinetic energy (KE) increases, what happens to potential energy (PE)?

Back

PE decreases.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

PE = mgh (mass x gravity x height).

Front

What is mechanical energy?

Back

The sum of potential energy and kinetic energy in an object.

Front

What is thermal energy?

Back

The energy that comes from the temperature of matter, related to the kinetic energy of its particles.
