Unit 1 Physics review

 Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800
• 400
• 0
• 200

Because displacement has a magnitude and direction it is called a ______. 

• distance
• vector
• arrow
• length

Distance and direction of an object's change in position from a starting point

• displacement
• distance
• motion
• reference point

Jerry walked from home to school, then from the school to the park. What is his total distance?

• 2 km

• 5 km

• 8 km

• 10 km

A person walks 50 meters directly north, stops, and then travels 32 meters directly south.  What is their displacement?

• 82 meters
• 18 meters
• 28 meters

How do we find speed?

• time x distance

• time - distance

• distance + time

• distance ÷ time

A car travelled 52 km in  ½h. Find the speed of the car.

• 104 km/h

• 85 km/h

• 26 km/h

• 17 km/h

When was the object sitting still?

• between 5 and 6 seconds

• between 2 and 5 seconds

• between 1 and 2 seconds

• between 0 and 1 second

At what point is the object moving back to the starting point?

At what point is the speed the greatest?

• C-D

• B-C
