Answer:
A. the energy an object has due to its motion
Step-by-step explanation:
"Kinetic energy" is the energy being produced by an object in motion. For example, when a person is running, he is producing kinetic energy. So this means that the faster the movement, the higher the object's kinetic energy while the slower the movement, the lower the object's kinetic energy. Speed and kinetic energy are directly proportional.
B. The energy derived from chemical reactions is chemical energy.
C. The energy an object has due to its position is potential energy.
D. The energy an object releases as heat is thermal/heat energy.
