Newton's First Laws of Forces

The  forces of motion

1.Force : A push or pull exerted by one object on another .
2.Friction : A force that opposes the motion of an object in contact with surface .
3.drag forces : a force that oppposes the motion of an object through a liquid or gas .
4. gravity : a force of attraction that exist between all objects with mass.
5. net force : the combined effct of alll forces acting on an object.
6.balanced force : forces that cancel each other out when acting together on a single object.
7. unbalanced forces : forces that do not cancel each other out when acting together on a single  object
8. inertia: the tendency of an object to opposes a chnge in motion.

Newton's Laws of Motion

First Law :
An object at rest remains at rest. An object moving in straight line will keep moving unless a force affect it.

Second  Law:
 The acceleration of an object is equal to the object mass times the object acceleration.
