Forces Test

For questions 1-4, draw the force diagram to represent the situation.

  1. The box is falling through the air (include Air resistance)


2.The box moves to the left at constant speed.

3.The weight pulls block A across a frictionless table.

4.The box is motionless.


For questions 5 -10, it is possible to have MORE THAN ONE correct answer. Circle all correct answers.

5.A hover puck(that has been turned on) resting on a table is given a brief push. A moment later, which of the following forces act on the block?

a.the force of the push

b.a normal force

c.kinetic friction

d.the force of gravity

6.Which of the following describes the motion of the hover puck? The puck

a.moves at constant speed

b.slows down gradually to a stop.

c.continues at constant speed for a while, then slows down

d.accelerates constantly.
For questions 7 - 10 refer to the diagram below. A student attaches a string to the hover puck on the table, and pulls steadily on the block. Circle the correct answer.

7.Which of the following forces act on the hover puck?

a.the towing force

b.a normal force

c.kinetic friction

d.the force of gravity

8.Which of the following describes the motion of the hover puck while it is on the table? The puck

a.moves at constant speed.

b.slows down gradually to a stop.

c.speeds up for a bit, then moves at constant speed.

d.accelerates constantly.

9.When the hover puck reaches point B, the string breaks. Which of the following describes the motion of the hover puck? The puck

a.moves at constant speed.

b.begins to slow immediately.

c.continues at constant speed for a while, then slows down.

d.continues to accelerate.

10. Eventually, the hover puck reaches the edge of the table. After the hover puck leaves the table, which of the following forces act on the puck?

a.the force of motion

b.a normal force

c.kinetic friction

d.the force of gravity

11. When you first learned how to roller skate, you may have gotten started by pushing off the wall at the skating rink. Draw a force diagram for yourself as you accelerate. Clearly label all the forces acting on you.

12. What are the factors that affect the frictional force on an object?

13. Explain the difference between mass and weight.

14. A student has a mass of 68 kilograms. What is his weight in newtons? Show all work and units.

15. If you push on an object with a force of 25 N and it moves at a constant speed what is the force of friction on the object?

  1. Net Force ______17. Looking at the force diagram below,

describe a possible motion for the

object. (All forces are the same size)
