Unit 1 Energy Study Guide Review

Potential Energy can be defined as:

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

• The energy an object has because it is moving.

• The process of energy being transferred from one object to another.

• The total energy of all particles in an object.

• The energy an object has due to its motion.

• The energy stored in chemical bonds.

• The energy produced by burning fuels.

Friction can be defined as:

• The force that resists the motion of two surfaces sliding against each other.

• The energy stored in an object due to its position.

• The process of heat transfer through a vacuum.

• The ability of an object to float on water.

Gravitational Energy can be defined as:

The Law of Conservation of Energy states that:

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

• Energy can be created but not destroyed.

• Energy is always lost during transformations.

• Energy can only be destroyed, not created.

A renewable resource is defined as:

• A resource that can be replenished naturally over time.

• A resource that cannot be replaced once used up.

• A resource that is always man-made.

• A resource that is only found underground.

A non-renewable resource is best defined as:

• A resource that cannot be replaced once it is used up.

• A resource that is always available and never runs out.

• A resource that can be quickly replenished by natural processes.

• A resource that is only found in renewable energy sources.
