Motion

Mechanical energy is broken into two types:

• chemical & physical

• solid & liquid

• potential & kinetic

• magnetic & gravitational

Stored energy is known as

• resting energy

• chemical energy

• sitting energy

• potential energy

Energy of motion is known as

• potential energy

• chemical energy

• moving energy

• kinetic energy

One form of energy can be converted into another. EXAMPLE: Chemical energy can be converted to kinetic energy

• true

• false

The change in an object's position.

• velocity

• movement

• motion

• direction

A fixed, unmoving object or location.

• key point

• reference key

• reference point

• coordinate

Another term used to describe speed is

• velocity

• rate

• acceleration

• motion
