7. An astronaut with a tool belt accidentally pushed off
from the shuttle and could not get back to the shuttle.
He threw his tools, one at a time, away from the
shuttle. Eventually, he was able to return to the shuttle
after throwing all of his tools from his tool belt.
Which of Newton’s laws was used in this scenario
to get the astronaut back to the shuttle?
a)
b)
c)
d)
Force of gravity and acceleration
For every action force, there is an equal and opposite
reaction force.
F=ma
An object in motion stays in motion unless acted on by
another force.
8. A dump truck moves more slowly when it is
filled with a load.
Which law of motion applies?
a) Force=Mass X Acceleration
b) Increasing the mass increases the force
needed to accelerate an object.
c) An object in motion remains in motion until
acted on by an outside force
d) Both a and b
e) Only a.
9. Which one of Newton’s laws would you use
to determine which object would be easier
to move?
a)
b)
c)
For every action there is an equal and opposite
reaction
An object at rest tends to stay at rest unless another
force is applied on the object
F=mXa
10. Which law is this demonstrating?
a) Equal and opposite
forces
b) The more mass
an object has, the
harder it is to accelerate.
c) Friction
d) None of the above
11. Looking at the same picture, which person
has more inertia?
a) the larger wrestler
b) the smaller wrestler

Inertia
d) none of the these
12. If you were to slide these books across a table,
one by one, the books would eventually stop their
motion. What force or forces are the cause of the
books stopping their motion?
a) Centrifugal force
b) Friction and gravity
c) Centripetal force and
Centrifugal force
d) Just gravity
13. Which of Newton’s laws is being demonstrated ?
a) Equal and opposite forces
b) Force = mass X acceleration
c) An object in motion stays in motion unless and outside force acts
upon it. An object at rest remains at rest unless an outside force
acts upon it.
14. Fuel burning in this rocket’s combustion chamber creates
gases. The rocket exerts a force on these gases to expel them
out of the nozzle at the bottom of the rocket. As a result, there
is an upward force exerted on the rocket by the gases.
Which of Newton’s laws
is being used in this
example?
a) For every action, there is an
equal and opposite reaction.
b) An object at rest stays at
rest unless another force is
applied.
c) The more mass an object
has, the harder it is to
accelerate.
14. If a swimmer pushes off of the pool wall
with a force of 100 N, how many Newtons of
force does the wall push back?
a) 50 N
b) 100 N
c) 0 N
15. Which law did you
use?
a) F=ma
b) Unbalanced forces
c) For every action, there
is an equal and opposite
Reaction.
