Physics Baseline Quiz

The position–time graph below shows the movement of an object. Depending on the information in the graph answer the questions below.

a. At what interval the object stops moving?

• A-B

• B-C

• C-D

• D-E

What interval shows that the object went back to its starting point?

• A-B

• B-C

• C-D

• D-E

The figure below shows the motion of an object along a straight line. If the object moved from point (A) to point (B) in 6 seconds, then went back to point (C) in 2 seconds. What is the total time of the trip?                                                                                 

• 6 seconds

• 4 seconds

• 2 seconds

• 8 seconds

The graph below shows the motion of a dog pacing along a fence. What is the total distance travelled by the dog?

The graph below shows the motion of a dog pacing along a fence. What is the dog final displacement?

Energy that is due to the motion of an object is

• kinetic energy.

• potential energy.

• gravitational potential energy.

• lastic potential energy

A force does work on an object if a component of the force

• is perpendicular to the displacement of the object

• is parallel to the displacement of the object.

• perpendicular to the displacement of the object moves the object along a path that returns the object to its starting position

• parallel to the displacement of the object moves the object along a path that returns the object to its starting position

What is the product of an object’s mass and its velocity?

• kinetic energy

• momentum

• impulse

• inertia
