Motion: Speed & Velocity

How do you tell if an object is in motion?

• By touching it

• Use of reference points

• Timing it for 10 seconds

• By physically pushing on it

The change in an object's position from starting point to ending point is called:

• Distance

• Velocity

• Displacement

• Acceleration

The distance an object travels in a certain amount of time is called:

• speed

• acceleration

• Velocity

• displacement

A car driving at 50 miles per hour drives for 2 hours. What distance did it cover?

• 50 miles
• 25 miles
• 100 miles
• 75 miles

What is the SI unit for speed?

• Mph

• m/s or km/h

• newtons

• m/s2

Average speed is an average of all of the speeds during a trip/distance

• True

• False

How fast is a train moving if it travels 32km in 4 hours?

• 8km/h

• 8m/s

• 128m/s

• 128km/h

Velocity differs from speed because velocity includes:

• speed

• direction

• distance

• height

Calculate the velocity of a cyclist traveling 100km south over a period of 5 hours

• 20km/h south

• 10km/h south

• 10mi/h

• 20km/h
