Practice Quiz: Position and 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. (a)   ​

• Yes
• Maybe

• No

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 (a)   are all needed to determine the position of an object.

• Reference Point

• Direction
• Object

• Position

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

• 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?

• Yes, both cars have the same velocity.

• No, both cars have different velocities.

• Yes, because they are moving at the same speed.

• No, because velocity includes direction.

• Line A

• Line B

• Line C

• Line D
