Question

If a person wanted to calculate how much kinetic energy an object has, the equation they would use would be: Question 2 options: PE=mgh KE=1/2 m v^2 W=F*d F=ma

Answer 1

Answer: $KE=\frac{1}{2}mv^{2}$

Explanation:

Kinetic Energy is the energy a particle, body or object possesses due to its movement and is mathematically defined as:

$KE=\frac{1}{2}mv^{2}$

Where:

$m$ is the mass of the body

$v$ is the velocity  of the body

So, if we want to calculate the kinetic energy $KE$ of an object, we have to use the equation given above.
