5.7AB Force and Motion Quiz

1. An engineer wants to test the ability of three materials to resist cracking. She drops a heavy metal ball from one meter above each test material. She can improve the investigation by—

• dropping a different size ball for each material.
• using materials that are the same thickness.
• testing only one material.
• using a feather instead of a metal ball.

2. A student set up an investigation in which he pulled a 100-gram block across four different surfaces. Which question is he most likely trying to answer?

• How does the surface affect the amount of force needed to move a 100-gram block?
• How does the mass of a block affect the amount of force needed to move it?
• How does force affect blocks of different masses?
• How does the surface affect the mass of a block?

3. The diagrams show two trials of an investigation in which the distance a ball rolls when released on cardboard ramps is measured. This investigation can be used to determine—

• how a ball’s mass affects the distance it rolls.
• how the material a ramp is made of affects the distance a ball rolls.
• how a ramp’s height affects the distance a ball rolls.
• how a ball affects a ramp’s height.

4. A student is investigating the effect of a sphere’s mass on the height it reaches when released from a spring launcher. What are TWO constant variables in this investigation?

• The sphere’s shape
• The spring launcher’s height
• The sphere’s mass
• How high each sphere is launched
• The amount of time each sphere spends in the air

1. A bowling ball is at rest on the floor. Which statement correctly describes the forces that are acting on the bowling ball?

• The forces are unbalanced, so there is no motion.
• The forces are balanced, so there is no motion.
• The forces are unbalanced, so there is motion.
• The forces are balanced, so there is motion.

2. A soccer player kicks a ball along a field. The diagram shows the position of the ball every 5 seconds as it is kicked. At one point, the student used a greater force to kick the ball to the next position. At which location did the student apply a greater force when they kicked the ball?

• Location 1
• Location 2
• Location 3
• Location 4

3. A fish is swimming in the river in the opposite direction than the river is flowing. The fish pushes forward with 10 Newtons of force while the water is flowing backward with 5 Newtons of force. Which statement describes the fish’s motion?

• The fish will move forward.
• The fish will move backward.
• The fish will stop moving.
• The fish will stop and then start moving.

4. A child pushes a toy truck so that it will roll along a track. Choose TWO sections of the track where the truck will experience an unbalanced force.

• Section 1
• Section 2
• Section 3
• Section 4
• Section 5
