Question

which two factors are used to calculate the kinetic energy of an object?
o gravity and velocity
o velocity and mass
o mass and volume
o volume and height

Explanation:

The formula for kinetic energy is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. So mass and velocity are used to calculate kinetic energy.

Answer:

velocity and mass
