Energy and Energy Transformations Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

At which point in a pendulum's swing is kinetic energy the greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

What happens to potential energy as a pendulum swings down?

Back

The potential energy decreases as the pendulum swings down.

Front

What happens to kinetic energy as a pendulum swings down?

Back

The kinetic energy increases as the pendulum swings down.

Front

What is the energy transformation when a battery powers a toy car?

Back

The energy transformation is chemical energy to mechanical energy.

Front

What is an example of potential energy in everyday life?

Back

A person sitting on a horse is an example of potential energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy transformation occurs in a light bulb?

Back

The energy transformation in a light bulb is electrical energy to light energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.
