4th law of motion by newton |
| Answer» Newton’s\xa0First Law of Motion\xa0also known as\xa0Law of Inertia\xa0states that every object persists to stay in uniform motion in a straight line or in the state of rest unless an external force acts upon it. In a simpler form, the first law of motion may also be stated as\xa0"If the net external force on a body is zero, its acceleration is zero. Acceleration can be non-zero only if there is a net external force on the body".Newton’s Second Law of Motion\xa0states that force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e.F = maThus,\xa0{tex}\\vec { F } \\propto \\frac { \\Delta \\vec { p } } { \\Delta t } \\text { or } \\vec { F } = k \\frac { \\Delta \\vec { p } } { \\Delta t }{/tex}, where k is a constant of proportionality,\xa0{tex}\\Delta p{/tex} is the change in momentum and p = mv.Newton’s Third Law of Motion:\xa0It states that "For every action, there is an equal and opposite reaction".<br>4th law ab tk newton n nhi diya... Newton gya...tum de skte ho...its ur choice...3 hi pdh lo<br>4th law????? are u searious?\u200d♂️?\u200d♂️ | |
