Unit 3 Force Summative Assessment Question Bank

**Teachers,

Feel free to use questions from this document to create your own test. This document will have the questions organized by standard, so you are able to pick questions that cover all the standards.

Benchmark 6.2.2.2.1

Recognize that when the forces acting on an object are balanced, the object remains at rest or continues to move at a constant speed in a straight line, and that unbalanced forces cause a change in the speed or direction of the motion of an object.

1. A car is traveling at a constant speed of 65 MPH. Is this an example of balanced forces or unbalanced forces?

1. balanced forces
2. unbalanced forces  

2. A car is sitting in a parking space. Is this an example of balanced forces or unbalanced forces?

1. balanced forces
2. unbalanced forces

3. A car is accelerating down a hill. Is this an example of balanced forces or unbalanced forces?

1. balanced forces
2. unbalanced forces   

4. A car turns a corner while staying at 15 MPH. Is this an example of balanced forces or unbalanced forces?

1. balanced forces
2. unbalanced  forces

Benchmark 6.2.2.2.2

Identify the forces acting on an object and describe how the sum of the forces affects the motion of the object.

5. The tendency of an object to remain at rest or in motion is known as ____________________.  

1. inertia
2. mass
3. force

6. Griffyn is riding his bike down the sidewalk when he accidentally hits a rock. Why does his body fly forward?

1. someone pushed him off
2. inertia kept him moving
3. gravity pulled him off the bike

7. What is friction?

8. List two forces that are in the image of the dog skateboarding.

9. Shawna is shopping at the grocery store. She puts a box of cat litter in the cart. Then she goes back and gets another box. How has the amount of force needed to move the cart changed from one box to two boxes of cat litter?

1. There is no change in force needed . Shawna is very strong.
2. There is less force needed because once the cart is moving it will stay moving longer.  
3. The cart will move faster due to more mass.  
4. There will be an increase in force needed to get the cart moving since the mass increased.

Benchmark 6.2.2.2.3

Recognize that some forces between objects act when the objects are in direct contact and others, such as magnetic, electrical, and gravitational forces can act from a distance.

10.    Using a Venn Diagram, compare and contrast the forces of electricity, magnetism, and gravity.

11.     What forces are both push and pull?

1. Electricity and Magnetism
2. Electricity and Gravitational
3. Magnetism and Gravitational
4. None of the above.

12.    Which force’s effect becomes stronger as an object comes closer to the source?

1. Electricity
2. Gravitational
3. Magnetism
4. All of the above

13.   Which force’s effects can be diminished or blocked?

1.  Electricity and Magnetism
2. Electricity and Gravitational
3. Magnetism and Gravitational
4. None of the above.

14.   Which force’s effects are dependent on the mass of the object?

1. Electricity
2. Gravitational
3. Magnetism
4. All of the above

Benchmark 6.2.2.2.4

Distinguish between mass and weight.

15. The weight of an object in space changes when it comes back to Earth.

1. True
2. False  

16.   The mass of an object will be different on Earth than it would be on the moon.

1. True
2. False  

17.    What is the relationship between mass and weight?

18. Brian and Claude have the same mass. Brian is on Earth. Claude is on the moon and claims that he now weighs less. Is he right? Why or why not?
