motion quiz

The distance an object moves divided by the time it took to move that distance.

• distance

• speed

• velocity

• acceleration

What is the total distance a car travels when it drives 1 lap on a 5 km track?

• 5 km

• 0 km

• 10 km

• 5 mi

How is velocity different from speed?

• it includes the displacement of the object

• it includes the direction of the object

• it includes the distance of the object

• it includes the acceleration of the object

When an object has a negative acceleration, it is:

• speeding up

• slowing down

• constant speed

A raft starts floating down a river at 2.6 m/s and hits some rapids. At the end of the trip, the raft is moving at 5.4 m/s after a trip of 6.1 seconds through the rapids. What is the acceleration of the raft?

Note: acceleration= (final speed- initial speed)/time

• 0.46 m/s²

• -- 0.46 m/s²

• 0.64 m/s

• 0.46 m/s

John is swimming at a speed of 1.6 m/s. He is swimming toward a boat floating on the water 500 m away. How long will it take John to reach the boat?

Note: Time = distance/speed

• 312.5 seconds

• 0.0032 seconds

• 31.25 seconds

• 0.032 seconds

Michelle is practicing riding her unicycle. She travels 15 meters until she falls off. It took her 2.4 seconds to complete the distance traveled. What is her speed?

Note: speed = distance/time

• 6.25 m/s

• 0.16 m/s

• 36 m/s

The speedometer on your car tells you

• average velocity
• instantaneous velocity
• average speed
• instantaneous speed

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time
