which two factors are used to calculate the kinetic energy of an object?\ngravity and velocity\nvelocity and mass\nmass and volume\nvolume and height
Answer
Brief Explanations:
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.
Answer:
B. velocity and mass
