The total path travelled by an object is known as...

distance

200

A jet flies 2600 miles in 5 hours. What is its average speed?

s = d / t

200

What are the units for distance?

meters (m)

200

What is the average velocity of a basketball that starts at half court, is shot into a net that is 20m away, and then brought back to be 1m in front of half court. It takes 100s.

What is the average velocity of the basketball?

.01 m/s

300

The total change in an object's position is known as...

displacement

300

A car starts at rest, and accelerates until it reaches a velocity of 18.6 m/s. If this takes 8 seconds, what was the acceleration of the car?

a = Δv / Δt 

300

What are the units for displacement?

meters (m)

300
