An object in motion stays in motion and an object at rest stays at rest until ...
a) Objects in motion naturally come to rest.
b) A constant force is required to keep it in constant motion
c) An unbalanced force acts on it
d) A balanced force acts on it
Inertia can be measured by using
a) force
b) velocity
c) mass
d) mass (x) velocity
Which object has more inertia
a) A tractor trailor rig moving at 2 m/s
b) A bowling ball rolling at 1 m/s
c) A pingpong ball rolling a 2 m/s
d) A car rolling at 5 m/s
A force is a
a) push or pull
b) measured in Newtons
c) all of the above
d) several can act together and be balanced or unbalanced
An accelerating car
a) has balanced forces acting on it
b) no longer has a force acting on it
c) has a constant velocity
d) has an unbalanced force acting on it
A rock sitting on a table has
a) has balanced forces acting on it
b) all of the above
c) an acceleration of 0 m/s/s
d) a velocity of 0 m/s
In order for a 1200 kg car to maintain a velocity of 4 m/s in a frictionless world how much force must be applied
a) 4800 N

Newtons first law of motion is sometime called the law of

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