Free points + brainliest? answer these correctly! as an object in motion becomes heavier, its kinetic energy a. increases exponentially b. decreases exponentially c. increases proportionally d. decreases proportionally

As an object in motion speeds up or "becomes heavier", its kinetic energy increases proportionally: double the velocity and you quadruple the kinetic energy. This is why a tiny bullet traveling at high speed does so much more damage than a huge truck bumping into something at 1 mph.

Choice C
