Can motion be turned into matter?

  1. Sep 9, 2014 #1
    Im wondering if motion can be turned into matter, since I heard that motion is like stored energy.
    Im not in any physics classes so I dont really know anything about the subject.

    edit: Im also wondering if this is true:
    Energy is effected by gravity, and movement is stored energy.
    So if a object is moving fast then its more effected by gravity.

    Thanks for reading, and im sorry if im not suposed to take two different questions in one topic.

    Yes, you can turn kinetic energy into radiation energy and then into matter:

    Here a recent thread on this:

    Not so sure

    Motion into matter? The usual definition for motion involves change in position over time but doesn't say anything about what is moving. Ergo, motion per se doesn't become matter.

    It's more accurate to say that radiation is released when moving material objects collide with each other, and that a reverse process is also possible.

    Position, velocity, force, mass, and energy are really concepts, not physical things.

    With this in mind, the answer the OP was given is correct. The relevant sciences are special relativity, general relativity, and quantum mechanics. All are difficult mathematically, but general-reader introductions to them are in print.
