Physics Test 2 Questions with Answers Graded A+
1. newtons 1st law A body at rest will remain
at rest or, if in mo
tion, will remain in motion
at constant velocity,
unless acted on by a net
external force."
2. newtons 2nd law The acceleration of a sys-
tem is directly propor
tional to and in the same
direction as the net
external force acting on
the system and is inversely
proportion to its mass."
3. newtons 2nd law
4. newtons 3rd law "Whenever one body ex-
erts a force on a sec
ond body, the first body
experiences a force
that is equal in magnitude
and opposite in di
rection to the force that it
exerts."
5. tension pulling force along an ob-
ject, typically a string, etc.
6. newtons 3rd law

7. support force that points perpendicular to a surface normal force
8. force due to surface roughness, friction
points parallel to surface
9. a force that acts on a body moving in a circular path centripetal force
and is directed toward the center around which the
body is moving.
10. An object sits at rest with no unbalanced forces acting The object will remain at
upon it. What do we expect this object to do? rest.
11. An object is traveling with a constant velocity with no The object will remain at
unbalanced forces acting upon it. What do we expect the same speed, traveling
this object to do? in the same direction.
12. An object sits at rest with an unbalanced force acting The object will begin to
on it. What do we expect this object to do? move with an increasing
velocity.
13. A car and a dump truck are involved in an accident and They experience the same
crash into each other. Assuming the only force acting is size force.
the force of collision, which one experiences the most
force during the crash - the car or the dump truck?
14. A car and a dump truck are involved in an accident and car
crash into each other. Which one will have the greatest
magnitude of acceleration during the crash? (Assume
the dump truck has a mass that is 4 times larger than
the car, and the only forces in the problem are those
between the two vehicles.)
