Unit 3 Review

During which interval is the object speeding up?

• A to B

• B to C

• D to E

• E to F

What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time 

Mr. Rudman speed walked 2 miles in 10 minutes, what is his speed?

• 0.2 miles/min

• 2 miles/min

• 20 miles/min

• 40 miles/min

On a distance vs. time graph, the steeper the slope _____

• the slower the speed

• the faster the speed

• less acceleration

• greater acceleration

What was the average speed of this object? (total distance/total time)

• 0.1 km/min

• 10 km/min

• 3.3 km/min

• it's at rest

What is the net force?

• 40 N left
• 0 N Balalnced
• 400 N right
• 40 N right

A 10 kg object is accelerated upward at 2 m/s².  What force is required? 

• 20 N
• 2 N
• 5 N
• 0 N
