INT Chapter 2 Review

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

Total distance divided by total time is

• average speed
• constant speed
• instantaneous speed
• acceleration

The correct equation to calculate velocity is

• distance/time
• time/displacement
• Δx × Δt
• Δx / Δt

Shona cycles at an average speed of 8km/h. How far has she traveled if she cycles for 4 hours? d=ts

• 55 km
• 32 km
• 43 km
• 32 mi

Which is correct?

• speed = distance x time
• speed = speed divided time
• speed = Distance divide time
• Speed = time x speed

Can be measured in meters per second (m/s)

• Displacement
• Time
• Velocity
• Acceleration

How fast will a person run if they run 10 miles in 100 minutes? s=d/t

• 10 mi/min
• 1000 mi/min
• 100 mi/min
• 0.10 mi/min

What units measure velocity?

• meters/second
• centimenters
• hours/kilometer
• kilometers

If a cheetah runs 180 miles in 3 hours, what is its average speed? s=d/t

• 60 hours
• 60 miles
• 60 miles/hour
• 60 miles/second/second
