1. A few weeks ago in a classroom right here…

2. PHYSICS

3. Test Review
Several physics students undertook the task of learning Newton’s 3 Laws of Motion. In the process of studying, they learned of The Force, which turns out to be equal to mass times acceleration. They learned much of The Force, like what different types of force are and how to draw a free body diagram. In due time (tomorrow) they would need to use their knowledge of The Force to destroy the imperial Chapter 4 test.

4. What units make up a Newton?kg
kg*m/s
kg*m/s2
kg*(m/s)2

5. Which of the following is not a part of a free body diagram?
The object
Arrow heads
Forces exerted by the object
Forces exerted on the object

6. A man pulls a sled with a force of 405 N to the East
A man pulls a sled with a force of 405 N to the East. His dog pulls it to the North with a force of 310 N. What is the magnitude of the net force on the sled?

7. As gravity from the earth pulls on an object:
The object does not exert a force on the Earth.
The object exerts a downward force on the Earth.
The object exerts an upward force on the Earth.
Newton’s Third Law does not apply.

8. A sumo wrestler pushes a 250 kg opponent with a net force of 52 N
A sumo wrestler pushes a 250 kg opponent with a net force of 52 N. How fast are the sumo wrestlers moving after 2.1 seconds?

9. A force of 20 N accelerates a 2 kg ostrich egg
A force of 20 N accelerates a 2 kg ostrich egg. What is the acceleration of the egg?

10. Newton’s 3rd Law of Motion Involves:
One object and one force
One object and two forces
Two objects and one force
Two objects and two forces

11. What is the weight of an 80 kg student on the earth
What is the weight of an 80 kg student on the earth? (Do not answer in pounds)

12. What is the mass of a 400 N Student on the Earth
What is the mass of a 400 N Student on the Earth? (Do not give your answer in pounds)

13. Draw a Free-Body Diagram of a text book sliding down a ramp with friction.
