Question

Are there any rules about forces and motion you can find out? What are they?

Could someone please help me with the above question. Thanks.

Answer 1

Rules about the forces and motion of the body are governed by 3 laws of motion. Namely Newton's 1st law, 2nd law and 3rd law.

First law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
