Physics 1 – Force Test Study Guide
1. What are accelerations produced by?
2. What is the acceleration when an object reaches terminal velocity?
3. You are pushing with 35 N on an object to move it at a constant speed. How much is the friction
force?
4. Your book weighs 7 N. What is the net force on the book when it rests on the desktop?
5. A 35 N falling object encounters 15 N of air resistance. What is the net force on the object?
6. How is acceleration proportional to mass?
7. A constant force pushes on a mass. What can you say about it’s velocity? What can you say about
it’s acceleration?
8. What is the terminal speed for a person in freefall? What is when the parachute is open?
9. When does equilibrium occur? (4 ways)
10. In what direction does a person’s weight vector act?
11. Draw a free body diagram for a box on a table being pushed to the right with a force greater
than friction. Describe the motion of the object.
12. Give some examples of fluids.
13. What forces are balanced when an object reaches terminal velocity?
14. What units make up a newton?
15. How is the magnitude of a force vector represented?
16. What is another name for gravitational force?
Problems
1. Calculate the force needed to cause a 50 kg object to accelerate at 3 m/s2?
2. Determine the acceleration produced by a constant force of 150N on a 50 kg object.
