The rate at which position is changing

• speed

• position

The location of an object relative to a reference point or origin.

• speed

• position

If the position is changing relative to a background, the object is said to be in

• speed

• motion

(Total distance travelled/Total time) or the average of all the instantaneous speeds.

• average speed

• instantaneous speed

The speed at a given moment in time

• average speed

• instantaneous speed

The 3 states of motion are

• fast

• rest

• slow

• accelerated

• uniform

An object's speed is constant and and its path is straight. What state of motion is this?

• rest

• uniform

• accelerated

An object's position is not changing with time. What state of motion is this?

• rest

• uniform

• accelerated

An object's speed is decreasing. What state of motion is this?

• rest

• uniform

• accelerated
