Answer:
I read about these, so:
1.F -an object can create force with the PRESENCE of energy.
2.F -POTENTIAL ENERGY is max at high position.
3.F -Sound energy is an example of KINETIC ENERGY.
4.T
5.T
6.F -KINETIC ENERGY depends on speed. Thus, if speed increases, kinetic energy increases.
7.F -the exchange of kinetic and potential energy is called MECHANICAL ENERGY.
8.F -Potential energy depends on height. So, if the coaster moves up, the potential energy INCREASES, while the kinetic energy decreases.
9.T
10.T
