Forces and Motion Review

Define force

• A force that describes movement.

• A force that acts against the motion of an object to slow it down.

• A substance that reduces the effects of friction.

• A push or a pull that causes an object to move, stop, or change direction.

Define reference point.

• north, south, east, and west.

• the location of an object.

• a point that is used to describe an object in motion.

• how fast an object is moving. S = d ÷ t.

Define lubricant.

• a substance that reduces the effects of friction.

• A force that acts against the motion of an object to slow it down.

• An invisible force that pulls objects towards one another.

• how fast an object is moving. S = d ÷ t

Define position.

• a point that is used to describe an object in motion.

• north, south, east, and west.

• the location of an object.

• a push or a pull that causes an object to move, stop, or change direction.

Define direction.

• a push or a pull that causes an object to move, stop, or change direction.

• north, south, east, and west.

• the location of an object.
