No force acts on a body moving with constant velocity. Explain |
|
Answer» Let a body of mass m is moving with constant velocity v. Then change in velocity (∆v)=0. Momentum (p)=mv then ∆p=m∆v=0 since velocity remains constant. F=∆p/∆t from newton 2 law. Ma=∆p/∆t. Ma=0/∆t. Ma=0 =F means force is zero F=m∆v/∆t=0. mass can not be 0. Means ∆v/∆t=0 V= constant Because the body is moving with constant valocity and if a force is added to it ... Then there is some change in the valocity of the body |
