Want this question answered?
what happens when a moving object speeds up,slows down,or changes direction?
yes. KE=1/2mv2, mass is also a factor that can change KE
We sum the two different speeds and devided by two
Air resistance
When two objects are moving with respect to each other at different speeds, and that difference is a good fraction of the speed of light, then the rate of time passing on one object would seem to an observer on the other object to be different.
Because they are all moving at different speeds.
An object can move in a circle at different speeds.
They're moving with all different speeds that cover a tremendous range.Their average speed depends on the temperature of the Quarter.
Refraction.
Sure. Kinetic energy depends on both mass and speed. So two objects could have different speeds, but if their masses are also different by just the right amount, their KE's could be equal.

It is only possible to escape the Earth's gravity by moving away from it at approximately seven miles per second. Seeing as it is very difficult to move at such high speeds by accident, it would not be possible to accidentally leave the atmosphere.

Yes. If a fan is moving faster, more work is having to be done to it and therefore more energy is being used.
Sunspots rotate at different speeds.
This depends on the parameters of the crystallization process or the possible grinding and sieving.
i dont know i am not that smart for that answer
