Answer: Option (a) is correct.
Explanation:
When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object.
The formula to calculate kinetic energy is as follows.
kinetic energy = \(\frac {1}{2}mv^{2}\)
where,
m = mass of object
v = velocity of object
Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
