Study Guide Chapter 12: Newton’s Laws and Gravity
1. Know each one of Newton’s 3 laws and examples of each.
2. Know how to solve a force = mass x acceleration problem and what units are used for force, mass and
acceleration
3. Know how to solve a weight problem (what are the variables and their units)? ALSO know what
weight is.
4. What is gravity on earth? How is it different than on the moon or in space?
5. How does air resistance effect falling objects? What if there was no air resistance – would they fall at
the same rate of acceleration?
6. What is inertia? Between a feather and a bowling ball, which one has greater inertia?
7. What force does a seatbelt provide?
8. What force acts on an object in free fall?
9. What is free fall acceleration and why is it the same for all objects?
10. What is projectile motion?
11. What determines an object’s momentum?
12. Know how to solve a momentum problem and what the units are.
13. Why does it require less fuel to accelerate a rocket in outer space than in Earth’s atmosphere?
