Motion, Acceleration, and Forces Review

An object that changes position relative to a reference point is

• stationary

• in motion

• moving at a constant speed

• moving at constant velocity

Average speed can be represented by the mathematical expression

• distance/time

• time – distance

• distance x time.

• time + distance

The ____________of an object consists of its speed and direction

• velocity

• average speed

• instantaneous speed

• displacement

The term for when an object speeds up, slows down, or changes direction

• Speed

• Velocity

• Acceleration

• Newtons

18 km/s in a northerly direction is an example of

• velocity

• Speed

• acceleration

• momentum

The net force of the following diagram is

• 20 N

• Moving to the left

• Balanced forces

• 160 N

Which graph best represents a graph of a car travelling down a freeway at a CONSTANT speed?

• A

• B

• C

• D

If forces acting on an object are balanced, then there _________ be a change in motion

• will

• will not

The snail is traveling at 5 cm/hr. This is an example of

• speed

• forces

• acceleration

• velocity

The runner's motion as they turned the curve to pass the baton is best described as

• speed

• force

• acceleration

• velocity
