Question

what is motion?

Answer 1

In physics, motion is a change in position of an object with respect to time. Change in action is the result of an unbalanced force. Motion is typically described in terms of velocity, acceleration, displacement and time .[1] An object's velocity cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in a closed system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum.


A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position.

Paul needs to learn to put quoted passages in quotation marks AND to tell where the information came from.

If he doesn't do these things, he's plagiarizing. =(

Answer 3

Ok, thanks

Answer 4

You're welcome. We aim to help keep our students out of trouble, too!! =)

There's nothing wrong with giving this kind of information, but just be sure to tell where you got it. And since students can't post links, all you have to include is something like this:
