Question

Which is the formula that describes the magnitude of an object's kinetic energy? A. kinetic energy = mass * (velocity)2 x 0.5

B. kinetic energy = mass x acceleration C. kinetic energy = mass x change in velocity
D. kinetic energy = mass x velocity​

Answer 1

A

kinetic energy=(mv²)/2

(1/2)(mv²)

(mv²)*0.5

where m=mass and v=velocity/speed
