Question

1. from \mechanical energy\... the sum of the kinetic and potential energy that an object uses to do work is called (6 points)

○ kinetic displacement
○ movement
○ mechanical energy
○ chemical energy

1. from \mechanical energy\... your body has potential energy stored inside as..... (6 points)

○ kinetic energy
○ chemical energy
○ mechanical energy
○ work

Explanation:

1. For question 14, the definition directly matches the term mechanical energy, which is the sum of kinetic and potential energy available for doing work.
2. For question 15, the human body stores potential energy in the form of chemical energy from food, which can be converted to other forms for movement.

Answer:

1. mechanical energy
2. chemical energy
