PHYSICS REVIEW

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is velocity?

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

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

Velocity is both ____ and _____. 

• speed , direction 
• direction, mass
• volume, density 
• direction, magnitude 

The unit we use to measure acceleration is ___. 

• meters / second 
• meters 
• seconds 
• meters / second / second 

The speedometer on your car tells you

• average velocity
• instantaneous velocity
• average speed
• instantaneous speed

What is this graph representing?

• Constant Speed
• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

At 60 seconds, how far had this object traveled? 

• 0 m
• 10 m
• 20 m
• 40 m
