Assignment Help:

Newton's second and  third law of motion:

Newton's second law of motion: If resultant force is acting on particle is not zero, and then acceleration of particle will be proportional to the resultant force and will be in direction of this force.

F = m.a

Newton's s third law of motion: The force of action and reaction between the interacting bodies are equal in magnitude and opposite in direction and are also having the same line of action.
