Newton and His Laws
(1642-1727)
This topic will be taught largely by example problems.
Initially we must define the concept of “force”:
A force is that which causes an object to accelerate.
, NEWTON I: (Newton’s First Law of Motion)
In the absence of external forces, an object at rest remains at rest
and an object in motion continues in motion at constant velocity (in
a straight line).
NEWTON II:
The acceleration of an object is directly proportional to the net force
acting on it and inversely proportional to its mass (F=ma).
NEWTON III:
If two objects interact, the force F12 exerted by object 1 on object 2
is equal in magnitude and opposite in direction to the force F21
exerted by object 2 on object 1 (F12 = - F21)
