2.
Which of the following is an example of a noncontact force?
a)
A foot kicking a soccer ball
b)
Drag working against an airplane
c)
Sun's gravitational pull on planets
d)
Air resistance working against gravity
3.
A bowling ball hits pins and sends them flying. Why does the bowling ball exert so much force on the pins?
a)
The bowler exerted force on the bowling ball, which then exerts force on the pins
b)
The bowling ball does not have as much mass as the pins, but it does have more force
c)
The bowling ball has greater velocity than the pins, but its force is not as great
d)
There are equal forces from the bowling ball and the pins
4.
Which 2 factors determine the strength of a gravitational field?
a)
Distance and mass
b)
Distance and time
c)
Mass and weight
d)
Electricity and magnetism
5.
Which of the following is true about an electrical field?
a)
It is weaker if the object making the field is very charged
b)
It is stronger if the object making the field is very charged
c)
It doesn't matter how charged the object making the field is
d)
Objects cannot have different charges
6.
Which statement is true about gravity?
a)
It is an attractive force that pulls all objects toward each other
b)
It is an attractive force that pulls everything toward the center of the Earth
c)
It is an attractive force that pushes all objects away from each other
d)
It is a repelling force that pushes all objects away from each other
7.
The weight of an 80 kg mass on Mercury is 296 N; the weight of the same 80 kg mass on Mars is 297 N. Mars has more mass than Mercury. Which statement explains why the weights of the object are so similar even though Mercury has less mass?
a)
Mars has no atmosphere, so it can't hold a gravitational field.
b)
Mercury is so close to the Sun that the Sun's mass increases the force of gravity.
c)
Mercury is so hot that the force of gravity is increased on all objects.
d)
Mars is not technically part of the solar system, so gravity doesn't influence it.
8.
Two objects have a certain gravitational force between them. What would happen if the distance between the objects increased?
a)
Their masses would also increase.
b)
Their masses would decrease.
c)
The gravitational force would also increase.
d)
The gravitational force would decrease
9.
We all know that inertia is a property of matter. What is the definition of inertia?
a)
The tendency of objects to resist a change in motion
b)
The tendency of objects to change motion without outside forces
c)
The tendency of objects to never move
d)
Bill! Bill! Bill! Bill! Bill!
10.
Why does the first sphere have a stronger gravitational force than the second sphere?
a)
The first sphere has more mass
b)
There is very little distance between them
c)
Both spheres actually have the same gravitational force
d)
The second sphere actually has more gravitational force
11.

a)
an equal and opposite reaction
b)
