• displacement
• distance
• motion
• reference point

What is the formula to calculate speed?

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

Kendra is walking home and her house is 200 m away. It takes her 20 seconds to get home. What was her speed?

• 400 m/s

• 200 m/s

• 25 m/s

• 10 m/s

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval
