What is the Kinetic Energy of a 2 kg object moving at a velocity of 12 m/s?
- 288 Joules.
- 24 Joules.
- 144 Joules.
Explanation from PART66Online
Kinetic energy is one half m v squared = 0.5 x 2 x 12 squared = 0.5 x 2 x 144 = 144 J. The 24 J figure is mass times velocity, dropping both the square and the half, while 288 J keeps the square but omits the half.

Ek=0.5*m*v^2
Ek=0.5*2*12^2
Ek=0,5*2*144=144 J
Ek=0.5*2*12^2
Ek=0,5*2*144=144 J
