1D Motion & Vectors Review

The graph above represents the motion of a car. Based on the graph, the car is most

likely—

• driving up a steep hill

• speeding up

• driving at constant speed

• decelerating

The graph to the right represents the motion of a cart.

What is the average speed of the cart?

• 0.5 m/s

• 2 m/s

• 2.5 m/s

• 5 m/s

Which pair of graphs represents the same motion of an object?

• 
• 
• 
• 

The diagram below represents the relationship between "velocity" and "time" for four cars, A, B, C, and D, traveling westward along a straight road.

Which car has the greatest magnitude of acceleration during the time interval 10 seconds to 15 seconds?

• Car A

• Car B

• Car C

• Car D

The graph to the right represents the relationship between the distance traveled and time elapsed for an object in motion.

Which of the following can be inferred from the graph?

• The object is moving along a curved path.

• The object is accelerating.

• The object is moving with constant speed.

• The object is decelerating.

• 15 m

• 24 m

• 44 m

• 88 m

An object starts from rest and falls freely. What is the speed of the object at the end of 3.00 seconds?

• 9.81 m/s

• 19.6 m/s

• 29.4 m/s

How long will it take an object to move 100 meters if the object is traveling with an average speed of 0.5 meter per second?

• 5 s

• 20 s

• 50 s

• 200 s
