Force & Motion

Force & Motion

Multiple Choice

A student records measurements and observations from two tests in a table.

Which question is the student likely testing?

• How do balanced forces impact the final speed?

• How do unbalanced forces impact the direction of motion?

• How do balanced forces impact the speed of motion?

• How do unbalanced forces impact the beginning speed?

Multiple Choice

Which table shows the likely result of increasing the force of a kick on the change in speed of a ball?

• A

• B

• C

• D

Multiple Choice

A tennis ball moves toward a tennis player, as shown.

The tennis player hits the moving tennis ball with the racket. How will the racket impact the ball?

• The racket will change the direction in which the ball moves.

• The racket will have no effect on the moving ball.

• The racket will allow the ball to move in the same direction with the same speed.

• The racket will allow the ball to move in he same direction with a different speed.

Multiple Choice

Which solution decreases the amount a shoe will slip on an icy surface?

• Make the bottom of the shoe more rough to increase the force of friction.

• Make the bottom of the shoe less rough to decrease the force of friction.

• Make the shoe taller to increase the force of gravity.

• Make the shoe shorter to decrease the force of gravity.

Multiple Choice

A student observes a diagram of the motion of a pendulum at four positions.

Which description predicts the likely motion of the pendulum after position 4?

• The pendulum will move immediately back toward position 3.

• The pendulum will move to the right to create a circle around point X.

• The pendulum will move to the left until it is at position 1, then back right.

• The pendulum will move to the right until opposite position 1, then back left.

Multiple Choice

A ball is attached to a spring, and the spring is attached to a wall, as shown.

A student pulls the spring to different lengths and measures how long the ball moves back and forth until it stops. The table shows the results.

Based on the observation, which prediction will most likely occur?

• When the spring is pulled 6 centimeters, the ball will move for more than 14 seconds.

• When the spring is pulled 30 centimeters, the ball will move for more than 14 seconds.

• When the spring is pulled 14 centimeters, the ball will move for less than 5 seconds.

• When the spring is pulled 27 centimeters, the ball will move for less than 6 seconds.

Multiple Choice

A student conducts an activity to find how the distance traveled by an object changes

with the amount of force applied to it. The student pushes a marble with varying

forces on the same surface and records the distances the marble travels before

coming to rest. The table shows the forces applied on the marble in different trials.

In which trial would the marble most likely travel the least distance?

• Trial 1

• Trial 2

• Trial 3

• Trial 4

Multiple Choice

A student rolls a toy car across different surfaces with the same amount of force and records the distances the toy car travels in a table.

Which statement accurately describes a surface’s amount of friction and its cause?

• Felt has the most friction because the toy car travels the least distance.

• Felt has the least friction because the toy car travels the greatest distance.

• Wax paper has the most friction because the toy car travels the greatest distance.

• Wax paper has the least friction because the toy car travels the least distance.

Multiple Choice

When gravity exerts a force on an object in the air, in which direction will the object

move?

• The object will move up.

• The object will move down.

• The object will move forward.

• The object will move backward.
