1st law of motion
It states that every object in this universe will continue in its state of rest or Uniform motion in a straight line,unless acted upon by some external force.
explanation
An object in its state of rest and pointing in some particular direction will remain in the same rest and in same direction , unless some force acts on the body.
2nd law of motion
It states that rate of change of momentum is directly proportional to the applied force and takes the direction in which the force is applied .
Explanation
Momentum is the force possessed by a body at some particular instant during its course of motion mathematically, momentum is the product of mass and velocity.
3rd law of motion
it states that 'to every action there is an equal and opposite reaction'
Explanation
It is very important to note that newtons third law applicable only when two bodies are involved
Examples are
When a boat man pushes the bank with a pole , the bank offers an equal and opposite reaction which makes the boat move forward.
