Motion Graphs

Multiple Choice

Which of the following statements best describes what a positive slope means in a motion graph?

• The object is moving backward.

• The object is moving forward.

• The object is at rest.

• The object is slowing down.

Multiple Choice

Which of the following best describes the motion of the person in the first set of graphs (position, velocity, acceleration vs. time)?

• The person walks forward at a steady speed without speeding up or slowing down.

• The person starts off not moving and then speeds up.

• The person moves backward at a steady speed.

• The person walks forward and then slows down.

Multiple Choice

Which graphs would show a straight line with no slope if an object is moving at constant velocity?

• Velocity vs. time and acceleration vs. time

• Position vs. time and velocity vs. time

• Position vs. time and acceleration vs. time

• Only position vs. time

Multiple Choice

What changes in the graphs when a person starts accelerating instead of moving at a constant velocity?

• The position vs. time graph becomes curved and the velocity vs. time graph becomes sloped.

• The position vs. time graph remains straight and the velocity vs. time graph becomes flat.

• The acceleration vs. time graph becomes zero.

• The velocity vs. time graph becomes horizontal.

Multiple Choice

Which graph best represents an object moving with increasing forward velocity?

• A straight horizontal line on a position vs time graph

• A straight diagonal line on a position vs time graph

• A curved line with increasing slope on a position vs time graph

• A curved line with decreasing slope on a position vs time graph

Multiple Choice

Two people moved in different ways. One walked forward at the same speed the whole time. The other started from rest and got faster and faster. Which sentence best describes how their motion was different?

• A. The first person had constant speed, and the second person had increasing speed.

• B. Both people stayed still the whole time.

• C. The first person slowed down, and the second person walked backward.

• D. Both people moved at the same speed the whole time.
