Question

Kinetic energy depends on

• A. mass
• B. speed
• C. frame of reference
• D. all of the above

Answer 1

The correct option is D all of the above

Kinetic energy of a body is given by

$K.E.=\frac{1}{2}m{v}^2$

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

Speed is different for different frames of reference.
