Question

State true or false.
Kinetic energy is proportional to the square root of the speed.

• A. True
• B. False

Answer 1

The correct option is B

False

$Kineticenergy\left(KE\right)=\frac{1}{2}m{v}^2$

where, $m$ is the mass of the body and $v$ is the speed of the body.

Kinetic energy is proportional to the square of the speed not the square root of the speed.
