Question

what is the energy of an object because of its potential and kinetic energies?
○ chemical energy
○ electrical energy
○ nuclear energy
○ mechanical energy

Explanation:

• Chemical energy is energy stored in chemical bonds.
• Electrical energy is related to electric charges and fields.
• Nuclear energy comes from nuclear reactions (fission/fusion).
• Mechanical energy is the sum of potential (stored due to position/configuration) and kinetic (due to motion) energy of an object. So the energy from both potential and kinetic is mechanical energy.

Answer:

D. mechanical energy
