Exam Review: motion, speed, vel, acc, forces

Carlos rides his bike from his house to school. It takes him 3 minutes to get there. If Carlos wants to calculate his speed, what other piece of information does Carlos need in order to figure out his speed?

• The time of day he is riding his bike.

• The distance between his house and school.

• The type of bike he is riding.

• The direction he needs to travel.

Two cars start traveling on the same road from the same place in the same direction. If two cars travel at different speeds for 2 hours and then stop, they will...

• end up on two different roads.

• move together most of the trip.

• travel different distances.

• arrive at the same place.

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

Total distance divided by total time is

• average speed
• constant speed
• instantaneous speed
• acceleration

A place or object used for comparison to determine if another object is in motion is called a

• comparison point
• reference point
• point of view
• motion detector

Change in speed over a given period of time is

• velocity
• motion
• speed
• acceleration

Acceleration of an object happens when things ________

• slow down
• go faster
• change direction (turn)
• All of the above
