Explain the laws of Newton.
First law
Newton's first law of motion states that a body at rest remains at rest or if in motion remains motion, moving in a constant velocity until it is acted upon by an external force. For example, imagine you are at rest. If you are pushed by a person, you will move, basing on the force applied on you. Similarly, imagine you are driving a car. When a sharp turn is taken, your body makes a jerk basing on the force applied on you because of turning.
Second law
Newton’s second law of motion stated that, the acceleration of an object produced by net force is directly proportional to the magnitude of the net force in the same direction of the net force and inversely proportional to the mass of the object.
The equation is,
a=F(net)/m Where, a=acceleration, F(net)=Net force, m=mass.
The equation can be rearranged as
F=ma
Third law
Newton's third law of motion 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.
