Unit Review Newton's Law of Motion

In order to determine an object’s location, you need a (a)   .

• time

• reference point

• speed

• displacement

Motion can be described through a change in (a)   .

• speed

• distance

• position

• time

To determine if an object has changed position, you need to know its position relative to another object.

• True

• False

Which of the following is the least useful object to use as a point of reference for describing the location of the parked car?

• the bird

• the streetlight

• the store

• the tree

Distance, a reference point, and a reference ________________ are all needed to determine the position of an object.

• direction

• speed

• mass

• temperature

A train traveled 250 kilometers (km) from its starting point in 5 hours (h). If the train continues at the same average speed for another 4 hours, how far will it have traveled from its starting point?

• 200 km

• 250 km

• 450 km

• 500 km

If you ride your bike around the block, returning to the exact point where you started, your displacement is ________________ m?

• 0 or zero

• 10

• 100

• 50

You are in a car going 70 km/h and another car passes you going in the opposite direction at 70

km/h. Do both cars have the same velocity?  Both cars have the same velocity. Do you agree?

• Yes, both cars have the same velocity.

• No, both cars have different velocities.

• Only one car has velocity.

• Neither car has velocity.
