Which of the following are true?If wrong explain
a)If a body is moving without being accelerated it means some force is acting on it.
b)If a body is at rest,no force is acting on it.
c)If a body is moving along a circular path with uniform speed some force is acting on it.

To answer each of these all you need remember is:



Please tell us what you think the answers are to these three questions, and why, and we'll check it for you.

Can u make it more clear...

Have you learned about Netwon's Laws of motion? My point was that if you know that applying a force to an object causes it to accelerate, and conversely if no force is applied to an object it does not accelerate, then you should be able to answer these questions. The only tricky one is (c) - to get it right remember that an object traveling in circular motion at constant speed is in fact accelerating towards the center of the circle.

One other thing - I know you're new here but please do not hit the "Disagree" response button unless you think my answer is factually incorrect. If you need further guidance simply ask a follow-up question, and be as specific as possible as to what you need help with.
