Unit 2 Motion Test Review

What is motion?

• An object's speed

• An object's change in position relative to a reference point

• The distance an object travels

• The time it takes to move

• Distance and direction

• Distance and time

• Time and acceleration

A frame of reference is:

• A picture frame

• A system for specifying the location of objects in space and time

• The speed of an object

• The path an object takes

What is the difference between distance and displacement?

• They are the same thing

• Distance measures path taken; displacement includes direction

• Distance includes direction; displacement measures path taken

• Distance is in meters; displacement is in seconds

A car travels 30 km north, then 20 km south. What is the displacement?

• 50 km

• 10 km north

• 10 km south

• 50 km north

What is the SI unit for speed?

• mph

• km/h

• m/s

• ft/s

Speed tells us:

• How fast an object moves

• The direction of motion

• Both speed and direction

• The acceleration of an object

Velocity tells us:

• Only how fast an object moves

• Only the direction of motion

• Both speed and direction

• The distance traveled

On a distance vs. time graph, what does the slope represent?

• Distance

• Time

• Speed

• Acceleration
