I. NEWTON’S FIRST LAW OF MOTION
1. Newton’s first law of motion is also known as the LAW OF ______INertia________________________________.
2. Newton’s first law says that
a. an object that IS NOT MOVING, or is at _______rest______________, will stay at _________rest__________, AND
b. an object that IS MOVING will keep moving with constant __________________________, which means at the same
_____________________ and in the same ________________________, UNLESS
c. an __________external/unbalanced_____________force acts on that object.
3. Which of the following has more inertia? a. Bowling ball or Tennis ball b. Hammer or Feather c. Sack of rice or pack of rice
II. NEWTON’S SECOND LAW OF MOTION
6. Newton’s second law of motion is also known as the LAW OF ____Acceleration__________________________________.
7. Newton’s second law says that When a ___________acts on an object the ___________will __________________of the net force.
8. The greater the force that is applied, the ____________________ the acceleration.
9. The lesser the force that is applied, the _____________________ the acceleration.
10. If the same force is applied to an object with a large mass, it will have a _______________________ acceleration.
11. If the same force is applied to an object with a small mass, it will have a _______________________ acceleration.
12. The equation that is used to solve second law problems is F = ma.
a. What do each of the variables mean?
F = ______________________ m = _________________________ a = __________________________
b. What unit of measurement must be used with each variable?
F = ______________________ m = _________________________ a = __________________________
III. NEWTON’S THIRD LAW OF MOTION
13. Newton’s third law of motion is also known as the LAW OF _______________________________________________.
14. Newton’s third law says that every time there is an ______________________________ force, there is also a
_______________________ force that is ______________________ in size and acts in the ____________________________
direction.
15. Newton’s third law states that forces must ALWAYS occur in ___________________________.
16. Listed below are ACTION forces. Tell the REACTION force.
a. Your bottom pushing on your desk seat -______________________
b. A bat hitting a baseball- _________________________________
c. Your finger pressing on your phone screen while texting-_____________________________
d. A flying balloon-_________________________________
IV. UNDERSTANDING…..
