1. Force and Motion Review

2. 1. A ball is rolling down the street
1. A ball is rolling down the street. Why doesn’t the ball keep rolling forever?
The ball will roll forever
The ball will go flat from rolling down the street
The shape of the ball keeps it from rolling forever
Friction acts against the ball’s motion, slowing it down

3. 2. Which force attracts two objects together?
Friction
Gravity
Work
Energy

4. 3. Which of the following lists different kinds of forces?
Solubility, gravity, density
Gravity, friction, magnetism
Magnetism, density, solubility
Friction, gravity, conductivity

5. 4. What would change about you if you traveled to the moon?
Mass
Weight
Height
All of the above

6. 5. What changes when an object is in motion?
Mass
Weight
Force
Position

7. 6. How can a soccer player make the ball go farther?
Run behind the ball
Kick the ball harder
Use a smaller ball
Keep the grass on the field long

8. 7. Which force keeps us here on Earth?
Centrifugal Force
Weight
Gravity
Motion

9. 8. What is force?
A push or a pull
The amount of mass something contains
The evidence that supports black holes
The Jedi mind trick that gets others to do what you want them to

10. 9. In the science lab students were measuring how far a car would travel over different types of surfaces: a rubber mat, a plastic folder, and a paper towel. What are they trying to measure in their experiment?
How does the amount of force it takes to make the car move?
How the size of the car affects how much force is needed to make it move?
How does the material the car travels over affects how far the car will move?
How does the amount of force affect how long the cars will continue to move?

11. 10. A teacher designs an experiment to test the effect of the width of a piece of bungee cord on the bungee cord’s ability to stretch. The teacher selects four pieces of bungee cord with different widths but the same length. Then the teacher attaches block with different masses to the pieces of bungee cord. What should the teacher do to improve this experiment?
Use block with enough mass to cause the four pieces to break
Use more than four pieces and four blocks
Use four piece of bungee cord with different lengths but the same width
Use blocks of equal mass on the four pieces of bungee cord.

12. 11. Two teams were competing in a tug of war competition
11. Two teams were competing in a tug of war competition. Team Isbell was able to defeat their opponent. What could be said about Team Isbell’s force in comparison to their opponent?
Team Isbell applied the greatest force in pulling
Team Isbell applied the greatest force in pushing
Team Isbell applied the least force in pulling
Team Isbell applied the least force in pushing

13. 12. A fifth grade class observes their teacher pull a block over various types of surfaces: wood, wax paper, sandpaper, carpet, and tile. Dependent on the surface the block was able to move freely. What conclusion could the students make based on their observations.
The ability for the block to move freely was based on the amount of friction.
The type of surface affected the amount of friction.
Friction is a type of force
All of the above

14. 13. Why is picking up something that is heavy more difficult than sitting it down?
The force of gravity is pulling the object toward the ground which makes the action of putting it down easier to do.
Pushing force is more difficult to accomplish than pulling force.
The force of gravity acts against you when you try to push something to the ground.
The action is less difficult because nothing is pulling the object toward the ground.

15. 14. With what tool do we measure force?
Bathroom scale
Triple-beam scale
Spring Scale
Thermometer

16. 15. The action of one surface or object moving over another is an example of what type of force?
Gravity
Friction
Magnetism
Buoyancy
