Newton's Second law of Motion - The rate of change of momentum is directly proportional to impressed force and it takes place in the direction of force acting on it. , Newton's Gravitational Law of motion - “Everybody attracts the other body. The force of attraction between any two bodies is directly proportional to their masses and inversely proportional to the square of the distance between them”., Newton's first law of Motion - “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called the law of inertia.”, Newton's Third law of Motion - “For every action there is an equal and opposite reaction”., Parallelogram Law of Forces - This law states that if two forces acting simultaneously on a body at a point are presented in magnitude and direction by the two adjacent sides of a parallelogram, their resultant is represented in magnitude and direction by the diagonal of the parallelogram which passes through the point of intersection of the two sides representing the forces.,
