negative kinetic energy
can kinetic energy be negative? When looking at the work function and all that jazz will kinetic energy ever be negative making it potential energy or is it only going to go to 0 at the lowest?

Re: negative kinetic energy
Kinetic energy can never be negative because of the way the equation works; ke = 0.5mv^2. 0.5 is a constant and mass is always positive. Only velocity could be negative, but since it's squared, the result is always positive, so kinetic energy can not be negative. I feel like you're blending some physics concepts into this, but for this class, I wouldn't think the prof would give us a problem that would have us determine our origin to determine if kinetic energy is negative.

Re: negative kinetic energy
Hello,
Kinetic Energy cannot be negative because of the way that the equations is set up: KE= 1/2 m(v)^2. Mass cannot be negative. The velocity can be negative but since it is squared, it always becomes a positive and as a result, kinetic energy will be positive as well.

Re: negative kinetic energy
Kinetic energy can be transformed into potential energy but it cannot itself be negative.

Re: negative kinetic energy
Kinetic energy cannot be negative because the terms within the equation used to find it all have to be positive thus producing a positive number.

Re: negative kinetic energy
Kinetic energy can never be negative because there is no such thing as a negative amount of energy.
