What is the law of motion |
|
Answer» Newton has given three laws of motion1) If a body is in rest or in an uniform motion then the body will remain in same state until and unles an external force is applied on it.This law gives the concept of force and inertia i.e. tendency to retain its position.2)The rate of change of momentum of an object is directly propportional to the force applird on it.This law gives the magnitude of force F~m(v-u)/t F~ma. (a=v-u/t) F=k.ma (K=1) F=maWhere F for Force,~ for directly proportional to,m for mass and a for acceleration.3)To every action there is equal and opposite reaction.Means if we apply force on an object then it will also apply reaction force on you.Some important points about 3 law are-1.Action and reaction acts in always pair.2.Action and reaction acts on different objects so they do not cancle eachother. \tNewton gave three laws of motion that describe the motion of bodies. These laws are known as Newton\'s Laws of motion.\tThey describe the relationship between the forces acting on a body and its motion due to those forces.\tThe three laws of motion were first compiled by Sir Isaac Newton in his work Principia Mathematica, first published in 1687. Newton used these laws to explain and investigate the motion of many physical objects and systems. |
