Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B
Chemical energy is converted to thermal energy and electrical energy.
C
Electrical energy is converted to chemical energy and thermal energy.
D
Mechanical energy is converted to potential energy which is then converted to kinetic energy.
