The kinetic energy of an object depends on which of the following?

A.
the object’s mass and direction

B.
the object’s speed and mass

C.
the object’s work and direction

D.
the object’s speed and work

Answer 1

KE = 1/2 m v^2

\[KE = \frac12 m v^2\]

Half times mass times velocity squared (equal to speed squared, because the act of squaring removes the information about direction)

Answer 2

So I feel like it might be B ?

Answer 3

Yep

Answer 4
