Two toy cars move in the same direction with velocities that are shown in the graph.

Based on the information in the graph, which statement describes the motion of the two toy cars?

• Car 1 is traveling faster than car 2.

• Car 2 is traveling farther than car 1.

• Car 1 has constant velocity between 0 and 10 seconds.

• Car 2 is changing direction between 10 and 15 seconds.

Which model has greater gravitational attraction (if any)

• Model A

• Model B

• Both Model A and Model B (same gravity)

What force brings the pencil down?

• Applied

• Magnetic

• Normal

• Gravitational

This force holds us to earth’s surface.

• friction

During a shot put event, athletes throw a very heavy round ball, called a shot, as far as possible. The

graph shows the vertical velocity of a shot that was thrown by an athlete.

Which statement is an accurate analysis of the vertical motion of the shot?

• The direction of the velocity is upward for both the first second and the last second, and the

  acceleration remains constant for the entire period.

• The direction of the velocity is downward for both the first second and the last second, and the

  acceleration decreases during the entire period.

• The direction of the velocity is upward for the first second and then downward for the last second, and

  the acceleration decreases during the entire period.

• The direction of the velocity is upward for the first second and then downward for the last second, and

  the acceleration remains constant for the entire period.

Students are exploring the relationship between velocity and acceleration. This graph shows the acceleration of a remote-controlled toy car.

Which statement is TRUE based on the graph?

• Segment BC and segment EF show constant speed.

• Segment OA and segment BC show constant speed.

• Segment AB and segment CD show positive acceleration.

• Segment OA and segment DE show positive acceleration.

What force causes objects to fall to the ground?

• Magnetism

• Gravity

• Friction

• Air resistance

What happens to the speed of an object if the force applied in the direction of its motion is increased?

• It decreases

• It stays the same

• It increases

• It stops

Which of the following is NOT a force?
