c. zero.
d. the force required to stop it.
e. none of the above

b. is the name given to the electrostatic force acting between surfaces sliding past one
another.
c. acts in a direction that opposes the motion of an object.
d. all of the above
e. none of the above
____
5. Compared to its mass on Earth, the mass of a 10-kg object on the moon is
a. the same.
b. more.
c. less.
____
6. The mass of a lamb that weighs 110 N is about
a. 1 kg.
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above
____
7. You would have the largest mass of gold if your chunk of gold weighed 1 N on
a. Earth.
b. Jupiter.
c. the moon.
____
8. Which has more mass, a kilogram of feathers or a kilogram of iron?
a. The feathers
b. The iron
c. Neither—they both have the same mass.
____
9. A bag of sports equipment has a mass of 10.0 kilograms and a weight of
a. 0.98 N.
b. 9.8 N.
c. 98 N.
d. 980 N.
e. none of the above
____ 10. Which of the following is NOT true about Aristotle’s concept of violent motion?
a. Violent motion is imposed motion
b. Violent motion has an external cause
c. Violent motion is the result of forces that push or pull
d. Violent motion is thought to be either straight up or straight down
____ 11. You and a friend are jumping on a trampoline. Why does Earth, which is rapidly orbiting around the sun, not
move under your feet when you jump?
a. There are different rules in space and on the surface of the earth
b. Newton’s first law holds that your body moves along with Earth because it is not
compelled to change its motion by an unbalanced force.
c. Newton’s second law holds that the acceleration produced by the force of gravity is offset
by the force of friction on your feet.
d. Newton’s third law holds that there is an equal and opposite force exerted by the
trampoline on your feet, which allows you to move with Earth through space.
True/False
Indicate whether the statement is true or false.
____ 12. The name of the astronomer who first publicly stated that Earth revolves around the sun is Galileo.
____ 13. Friction refers to the force between two surfaces that are sliding past each other.
____ 14. A force can be simply defined as a push or a pull.
____ 15. Inertia is the property that every material object has; inertia resists changes in an object's state of motion.
____ 16. If a hockey puck were to slide on a perfectly frictionless surface, it will eventually slow down because of its
inertia.
____ 17. If you were to slide a hockey puck across a frictionless ice rink, there must be a horizontal force on it to keep
it in motion.
____ 18. The amount of matter in an object is its weight.
____ 19. The SI unit of mass is the newton.
____ 20. The force due to gravity acting on an object is its mass.
____ 21. The SI unit of force is the kilogram.
____ 22. An astronaut weighs the same on Earth as in space.
____ 23. An astronaut has the same mass on Earth as in space.
____ 24. The reason a penny thrown straight up inside an airplane will come back to your hand is that you, the air
inside the plane, and the penny are all moving at the same horizontal velocity.
____ 25. In the fourth century B.C., Aristotle divided motion into two types: natural motion and violent motion.
Problem
26. On the surface of Jupiter, the acceleration due to gravity is about 3 times that on Earth. How much would a
0.40-kg rock weigh on Jupiter?
27. On the surface of Jupiter, the acceleration due to gravity is about 3 times that of Earth. What would be the
mass of a 170-kg rock on Jupiter?
