Q21

. . . . . . . . has two types of energy?

A.
Mechanical
Answer
B.
Electric
C.
Chemical
D.
Sound

Answer: Option A

Solution

Answer: Option A
Solution:
The correct answer is A: Mechanical.

Mechanical energy is the energy an object has due to its motion or position.
It's actually the sum of two types of energy:
    Kinetic energy: This is the energy of motion. Any moving object has kinetic energy (like a rolling ball).
    Potential energy: This is stored energy based on an object's position or condition. For example, a ball held high above the ground has gravitational potential energy.
Electric energy is associated with the flow of electrons and electric charges.
Chemical energy is stored in the bonds of atoms and molecules. It's released during chemical reactions (like burning wood).
Sound energy is energy that travels as waves through a medium (like air or water).
Therefore, only mechanical energy is defined as having two distinct types (kinetic and potential).
