Energy Test (-open)

Front

What is mechanical energy?

Back

The total amount of kinetic and potential energy in a system.

Front

What happens to gravitational potential energy (GPE) and kinetic energy (KE) when an object is dropped?

Back

GPE goes down, KE goes up.

Front

What type of energy increases with the height of an object?

Back

Gravitational potential energy.

Front

Why does your hand feel cold when holding an ice cube?

Back

Heat flows from your hand to the ice cube.

Front

What happens to the kinetic energy of water when it is heated from 10°C to 20°C?

Back

The kinetic energy increases.

Front

Define 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

Explain the law of conservation of energy.

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is gravitational potential energy?

Back

The potential energy held by an object because of its height above the ground.

Front

How does temperature affect the kinetic energy of particles in a substance?

Back

As temperature increases, the kinetic energy of the particles increases.
