Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

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 energy transformation occurs in a toaster?

Back

Electrical energy is transformed into thermal energy.

Front

What type of energy does a slingshot have when held back?

Back

A slingshot has potential energy when it is held back.

Front

Which object has kinetic energy?

Back

A ball thrown across the yard has kinetic energy.

Front

What happens to a skier's potential and kinetic energy when skiing down a slope?

Back

As a skier goes down a slope, their potential energy decreases while their kinetic energy increases.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

Can energy change forms? Give an example.

Back

Yes, energy can change forms. For example, when you rub your hands together, mechanical energy is transformed into thermal energy, making your hands warm.

Front

What is an example of thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. An example is the heat produced by a stove.
