Expert Answer:

Newton's first law of motion
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

Newton's second law of motion states that rate of change of momentum of an object is directly proportional to the applied force and takes place in the direction in which the force acts. 
Thus, 
F o r c e space alpha fraction numerator C h a n g e space i n space m o m e n t u m over denominator T i m e space t a k e n space end fraction
T h u s comma space
F space equals space fraction numerator m left parenthesis v minus u right parenthesis over denominator t end fraction... left parenthesis 1 right parenthesis
 
Where, 
F - Force applied
m - mass
v - final velocity of an object 
u = initial velocity of an object
 
Newton's third law of motion
For every action there is equal and opposite reaction.
