| 6928. |
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 |

An astronaut in open space is away from his ship.How can he return to his ship.? |
|
Answer» Yes,thanx a lot. We know that in space astronaut are with aerosol . Spray the aerosol in opposite direction of spaceship. You will get some velocity in the direction opposite to the direction of spray. So you will move towards the spaceship and can reach there. Here the law of conservation of momentum is used. I hope you have got your answer. Why will he go away from his ship |
