Kinetic energy can never be negative true or false?

True. Ek = 1/2mv^2





Mass can never be negative, and any negative number that is squared is always positive [e.g. 6^2 = 36, (-6)^2 = 36]


so positive x positive = positive





It is also a form of energy which is a scalar quantity (no direction) and energy is always positive.Kinetic energy can never be negative true or false?
it is true. KE= .5 mv^2. the mass is never negative and since the velocity is squared there is no number that can cause KE to be negativeKinetic energy can never be negative true or false?
ek=1/2mv2


it can definitely be negative. If m is a negative and you times it by 1/2 and then v2 (squared) it will still be negative.





Example:





ek=1/2x-2x4(squared)


ek= -1x16


ek= -16
True. Because mass is always positive and velocity cannot be negative, only positive in a diferent direction!
true KE= 1/2mv^2





mass can never be negative and if velocity is squared then it can only be positive
true that kinetic energy can never be negative, but delta KE can be, that is, obviously, you can have a negative change in kinetic energy, but it'll just be moving from a positive value to a smaller, but still positive value.
kinetic energy can never be negative,but in calculations,negative answers can be gotten,but the negative sign as no effect on the answer but tell us about the direction of the energy
