1) An object in motion stays in motion and an object at rest stays at rest until ...
A
A balanced force acts on it
B
An unbalanced force acts on it
C
Objects in motion naturally come to rest.
D
A constant force is required to keep it in constant motion
2) Inertia can be measured by using
A
velocity
B
force
C
mass
D
mass (x) velocity
3) Which object has more inertia
A
A car rolling at 5 m/s
B
A bowling ball rolling at 1 m/s
C
A tractor trailor rig moving at 2 m/s
D
A pingpong ball rolling a 2 m/s
4) A force is a
A
push or pull
B
several can act together and be balanced or unbalanced
C
all of the above
D
measured in Newtons
5) An accelerating car
A
has balanced forces acting on it
B
has a constant velocity
C
has an unbalanced force acting on it
D
no longer has a force acting on it
6) A rock sitting on a table has
A
has balanced forces acting on it
B
a velocity of 0 m/s
C
all of the above
D
an acceleration of 0 m/s/s

A
4800 N
B
300 N
C
0 N
D
4 N
8) Newtons first law of motion is sometime called the law of

statics
B
inertia
C
balanced forces
D
unbalanced forces
9) Two books are laying on a table top. With out picking them up how could you determine which has the greatest inertia
A
look at them the larger one will have more inertia
B
it is impossible to tell
C
give each one a push, the one that moves the easiest has less mass thus less inertia
D
neither one has inertia they are not movinh
