i have some questions i cannot find the answer to in my physics book or in my notes, so if you can answer any of these, it would be a BIG help. Thank you if you can!
Circular motion
1) in what direction does centripetal force act?
2) how can a rotating object simulate gravity?
Gravity
3) what happens to the force of gravity as you get farther away from the center of gravity?
4) which pulls harder, earth on the moon or the moon on the earth?
Heat, Temp, and Expansion
5) what causes some materials to have higher specific heats than others?
6) how does waters specific heat effect the environment of earth?
Thermodynamics
7) how do you make a heat engine more efficient?
8) what happens to the temperature of a system when work is done on it?
9) what happens to the temperature of a system when it does work?
10) what happens to the temperature of air when it is compressed? when it expands?
thanks!
