Question

Which is the correct equation for calculating the kinetic energy of an object?

K times E = m times g times h.

K times E = one half m v squared.

K times E = one half a t squared.

K times E = one quarter g squared.

Answer 1

Any ideas?

Answer 2

Great job!

Answer 8

wow thx

Answer 9

NP!

Answer 10

i didnt think i was going to get it correct

Answer 11

:)

Answer 12

first eqn is gravitational potential energy
second is kinetic energy
the third is a kinematic eqn assuming initial velocity = 0
And off the top of my memory I am not sure what the 4th is
