Topic 6: Forces and Motion Test

Look at the path a golf ball travels once it is struck by a golf club.

In what order are forces acting on the ball?

• gravity, push, friction

• friction, gravity, pull

• pull, push, gravity

• push, gravity, friction

Christopher investigated force and mass by applying the same force on three different objects. He recorded his observations in a table.

What can Christopher do so that object 3 moves about the same distance as object 1?

• Perform more trials on all three objects.

• Increase the force applied on object 3.

• Perform more trials on object 3 only.

• Increase the force applied on object 1.

Bella investigated forces by sliding blocks made of different materials down a ramp. She recorded the time it took for each block to reach the bottom of the ramp in this table.

Which statement is a correct analysis of Bella’s data?

• Gravity had the least effect on Block 2.

• Gravity had the greatest effect on Block 2.

• The least friction occurred between Block 1 and the ramp.

• The most friction occurred between Block 1 and the ramp.

A student investigates force and motion. She measures the mass of four wood blocks and places the blocks on a smooth surface. She will push each block with an equal amount of force and measure how far each moves with a ruler. Then, she will place the blocks in order based on how far they move when pushed.  Which best predicts her results in order, from the block that moves the farthest to the block that moves the least?

• 1,2,3,4

• 1,3,2,4

• 4,2,3,1

• 3,1,4,2

Gina is helping her family move. She tries to push a desk, but she can only move it very slowly. She asks her brother to help, and they begin to push the desk together.

What happens to the movement of the desk and why?

• The desk moves slower than it did before because more force is applied.

• The desk moves faster than it did before because less force is applied.

• The desk moves faster than it did before because more force is applied.

• The desk moves slower than it did before because less force is applied.

The person kicks the ball in the image below 20 meters. Suppose the soccer ball in the image is replaced by one that is twice the mass of a regular soccer ball.   How could the person kick the ball the same distance as the first soccer ball?

• kick the ball in a different direction

• kick the ball with the other foot

• kick the ball with less force

• kick the ball with more force

Students investigate forces and how they affect objects. They use a small cart and wooden blocks to carry out their investigation. They pushed the cart and blocks 10 times, using the same amount of force. Each time, they added 5 more blocks to the wagon. They measured how far the cart moves each time. They made a line graph to show their results.

What will their graph show?

• The distance the cart moves decreases as the number of blocks in it increases.

• As the number of blocks in the cart increases, the distance it moves stays the same.

• The distance the cart moves is not related to the number of blocks in it.

• The distance the cart moves increases as the number of blocks in the cart increases.

Nicole investigated force by applying different forces to the same object and measuring how far the object moved.

She recorded her observations in a table.

Which conclusion can be supported by the evidence shown in Nicole’s observation table?

• Force has no effect on motion.

• Forces cannot be accurately measured.

• A greater force causes a greater change in motion.

• Trials always give different measurements
