Newtons 3 laws
Can draw a free body diagram and
apply Newtons laws to it.
Newtons first law:
Law of inertia,
If all of the forces acting on an
object balance so that the net
force is zero, then
a) the object must be at rest.
b) the objects speed will decrease
c) the object will follow a parabolic
d) the objects direction of m
