Laws of physics
1. Newton’s laws of motion
i) The 1st law of states that body will continue to be in a state of rest or uniform motion in a straight line unless an external force is applied.
ii) The 2nd law of motion states that the rate of change of momentum of a body is directly proportional to the external fore and take place in the direction of the force, f= ma
iii) The Newton’s 3rd law of motion states that to every action there is an equal but opposite reaction.
2) The laws of thermodynamics.
a) The 1st law states that The total thermodynamic state of a system is equal to zero.
b) The 2nd law of thermodynamics states that In a cyclic process enthropy will either increase or remain the same, In terms of energy conservation it states that energy transformation is not hu se more http://www.physicslectures.info/2016/02/read-50-laws-of-physics.html
