When a heavy football player and a light one run into each other, who exerts more force?
a)
The heavy one
b)
The light one
c)
They are equal
d)
there is no such thing as force
2.
friction is a force that acts
a)
in the same direction as the motion
b)
opposite to the direction of the motion
c)
opposite to the applied forces
d)
the same direction as the applied force
3.
A 20 kg bike accelerates at 10 m/s2. what was the force
a)
25
b)
200 N
c)
20 N
d)
10 N
4.
What is the acceleration of the object from point O to A?
a)
0m/s2
b)
2m/s2
c)
10m/s2

5.
If lil Wayne, who is an alien, weighs 578 Newtons on Earth and 96 Newtons on the moon, this means that his...
a)
mass is greater on earth.
b)
mass is greater on the moon.
c)
inertia is greater on earth and less on the moon.
d)
mass is the same on the moon and the earth.
6.
Which best explains why we are able to accelerate forward when starting to run?
a)
As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
b)
No acceleration takes place. Runners are always at a fixed velocity.
c)
The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
d)
The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward
7.
