Newton's first law of motionA body will remain in its state of rest or
motion at constant velocity unless a
non-zero
resultant/net force acts on it.
, Newton's second law of motion
When a net force acts on an object, the object
will accelerate in the direction of the force
and the acceleration is directly proportional
to the force and inversely proportional to the
mass of the object.
,Newton's second law of motion in terms
of momentum
The net (or resultant) force acting on an
object
is equal to the rate of change of
momentum
of the object in the direction of the net
force.
, Newton's third law of motion
When object A exerts a force on object B,
object B SIMULTANEOUSLY exerts an
oppositely directed force of equal
magnitude on object A.
