Unit 3 Force and Motion Test Corrections

1

A student wants to experiment to determine how the height of a ball dropped in a box of sand will affect the crater size it will make in the sand.

What other piece of equipment will be most useful in conducting this experiment?

1

A student wanted to test the effect of friction on a toy car rolling down a ramp. She has constructed the ramp with five lanes, each covered with a textured material.

She rolled a toy cart down each lane and used a timing device to measure the length of time it took the cart to reach the end of the ramp. Her results are shown in the chart below.

Refer to the information above. What conclusion could the student make based on this experiment?

1

A student pushes a wagon, and it begins to move in the direction shown. Describe the forces acting on the wagon.

1

The force of friction was less on the left so the box moved to the right.

What can be said about the effect of the force being applied by the student on the left?

1

Which type of force will not change the motion of an object?

2

This question has two parts. First, answer Part A. Then, answer Part B.

Two students are investigating force. In this experiment, the students place cardboard ramps on different stacks of books. The students measure how far that cars with the same mass will travel when released from the top of the ramp. The set up the students use is shown below.


Part A
Which question is the group best trying to answer with this experiment?  __________

Part B
Why is the length the car travelled different in each trial?  __________

1

Two students want to move a cart full of bricks. Which actions will make moving the cart in one direction the easiest for the students?

1

Which term best describes the forces acting on the box shown?

1

Students use a spring scale to measure the differences in force when a block is moved across smooth and rough surfaces. What unit of measurement should the students use when recording the data?

1

Describe the motion of the box shown based on the forces that are being applied to it.

1

Which direction will the ball move after the student kicks the ball?

1

Select the two statements that are true about this tug-of-war game.

The table shown describes examples of different forces. Identify the force described in each column.

Drag the correct answer to each box.

Gravity
Magnetism
Friction
