Unit 2 Study Guide-Motion, Forces, & Energy
Answer all questions in your composition book!
Define the following terms:
-Single Force-Force
-Combined Force-Magnitude
-Opposing Force-Net Force
-Balanced Force-Friction
1. What is the formula associated with Newton’s second law?
**Know how to solve problems using this formula!
2. Set up 3 sample problems for calculating force, acceleration or mass using this formula. Trade your sample problems with a neighbor.
3. Using Newton’s second law, how will the force be different for pushing a heavy object vs a lighter one?
4. Using Newton’s second law, how will the acceleration be different for pushing a heavy object vs a lighter one with the same force?
5. What is the formula for Net Force?
**Know how to solve Net Force using this formula!
6. Set up 3 sample problems involving Net Force to trade with a neighbor.
7. What does it mean when forces are balanced (with respect to motion)?
8. How does the mass of an object affect its force if we want to increase the speed? How about decrease its speed?
9. What two things give an object its momentum?
10. How does the surface area of an object affect friction?
11. What factors affect friction?
12. Draw a comic strip that shows an example of air resistance and gravity. Label the forces involved using vectors.
