How do changes in the mass of an object affect its motions?

if by motion you mean movement then the objects weight would change and it's mass so if it were heavier it might move slower. But if going down at a 145 degree angle then it would it would go slow then become faster as it goes down more. if it were lighter then it would go fast and continue to be fast until stopped by a force more powerful than it's own.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
