Question

the energy of motion is known as
a kinetic energy
b heat energy
c potential energy
d magnetic energy

Explanation:

To solve this, we recall the definitions of each energy type:

• Kinetic energy is the energy an object has due to its motion.
• Heat energy is related to the temperature and internal energy of a system, not just motion.
• Potential energy is stored energy (e.g., due to position), not energy of motion.
• Magnetic energy is related to magnetic fields, not motion.

So the energy of motion is kinetic energy.

Answer:

a. kinetic energy
