Question

Which of these is not a conservative force and does not have a form of potential energy connected with it?

gravity, electric attraction and repulsion, friction, or magnetic attraction and repulsion?

**I think it is friction.. is that correct?

Which of these is true about kinetic energy but not necessarily true about potential energy?

A. The kinetic energy of an object is never negative.

B. Kinetic energy depends on position.

C. Kinetic energy increases with height.

D. Kinetic energy is a scalar.

**Not sure about this one at all though :( Thank you!!
