1. measure of the force of gravity on an object
weight
2. force that keeps two objects that are touching from easily sliding past each other
friction
3. any push or pull
force
4. change in the speed or direction of an object's motion
acceleration
5. force that pulls all objects toward each other
gravity
6. pushing a grocery cart is an example of a _________
force
7. riding your bike down a hill, slowing down, and turning are examples of ___________
acceleration
8. motion is stopped and started by _________
forces
9. How would the weight of an object change on the moon?
It would weigh less because the moon has less mass, and therefore less gravity
10. What happens to the speed of an object if the force applied to the object increases?
The object moves faster.
11. If friction did not exist, could you stop a bike that you were riding? Why or why not?
No, because the bike would keep slipping without any friction.
12. Why would you weigh less on Mars than on Earth?
Mars has a smaller mass than Earth, so there is less gravity there.
