Numericals are the physics problems which are to be solved by applying physics formulae and the theoretical knowledge. 
 
The first Newton's law of motion states that - A body continues to be in a state of rest or in a state of uniform motion along a straight line unless acted upon by an external unbalanced force.
The second Newton's law of motion states that- The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts. 
The third Newton's law of motion states that-To every action, there is an equal and opposite reaction.
