Since in space there is no friction, so if a body is given a force once then does it stop or does it continues to move or do work without stopping forever (until something stops it )?

Solution

According to Newton's second law F=ma. This means if we push on an object and there is no other forces balencing that force, the object will accelerate. As soon as we stop pushing on it, it stops accellerating unless there is another force acting on it. So if there was no friction the object would move forever, but remain at a constant velocity (no acceleration).

We saw in Newton's laws of motion that if we apply an external unbalanced force on a ball,it will move and also will come to a stop because of gravitational pull and also frictional force. If we do the same thing in space,will the ball come to a stop?

Because,in space there is no frictional force and no gravitational pull,so will it come to stop?

Q. Friction is such a force that slows down or stops a moving body as it opposes___.

Q. A moving bicycle comes to rest after some time if we stop pedaling it. But Newton's first law of motion says that a moving body should continue to move forever unless some external force acts on it. How do you explain the bicycle case?

Newton's first law says that if a body is at rest it remain at rest but if a body is moving in uniform linear motion it keep moving on and on and on untill a external force is applied ,so when I slip my book in straight line it stops after 3 s how this is done which force is stopping my book to keep moving .

Q. It is possible to exert a force which does work on a body without clinging its kinetic energy? If so, give example.
