Question

Mention the type of energy (i.e. kinetic energy$K$or potential energy $U$) possessed in the following cases.
(i) A moving bus

Answer 1

Step 1: Recall the concepts of kinetic energy

The kinetic energy of an object is the energy that it possesses due to its motion.

Mathematically, $E_k=\frac{1}{2}m{v}^2$
Where $E_k=$Kinetic Energy
$M=$mass of the body
$V=$velocity of the body

Step 2: Energy possessed by a moving bus

1. In a moving bus, the bus has some mass and it travels with some velocity.
2. As the bus has both mass and velocity, it possesses kinetic energy.

Thus, a moving bus posses kinetic energy $\left(K\right)$.
