Final Energy Test

Front

What type of energy is stored in an object when it is compressed or stretched?

Back

Elastic potential energy

Front

What is potential energy due to gravity called?

Back

Gravitational potential energy

Front

What does the Law of Conservation of Energy state?

Back

Energy is never created or destroyed; it is only transformed from one form of energy to another. The total amount stays the same.

Front

How does the thermal energy of a larger beaker of liquid compare to a smaller beaker?

Back

The liquid in the larger beaker has more thermal energy than the liquid in the smaller beaker.

Front

What is the energy transformation when a lamp is plugged into a wall socket and turned on?

Back

Electrical to radiant and thermal

Front

What is mechanical energy?

Back

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

Front

Define kinetic energy.

Back

The energy an object has due to its motion.

Front

What is thermal energy?

Back

The total energy of all the particles in an object, related to temperature.

Front

What is the formula for gravitational potential energy?

Back

PE = mgh (where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height).

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
