• nonmechanical energy

• kinetic energy

which of the following energy forms associated with an object due to its position?

• potential energy

• positional energy

• total energy

• kinetic enerdy

which of the following energy forms is not involved in hitting a tennis ball?

• kinetic energy

• chemical potential energy

• gravitational potential energy

• elastic potential energy

If friction is the only dissapated energy of an object during a given physical process, which of the following assumptions can be made in regard to the objects kinetic energy?

• The kinetic energy decreases

• The kinetic energy increases

• The kinetic energy remains constant

• The kinetic energy decreases then increases

the main difference between kinetic energy and potential energy is that

• kinetic energy involves position, and potential energy involves motion

• kinetic energy involves motion, and potential energy involves position

• although both energies involve motion, only kinetic energy involves position

• kinetic energy involve position, only potential energy involves motion
