WebBeautifully put by a review done by the Khan Academy, kinetic energy cannot be negative, but the fluctuations in direction can be negative. This idea means the energy itself can never be a negative value, but where the force is traveling can depict its negative effect. WebKinetic energy is a form of energy associated with the motion of a particle, single body, or system of objects moving together. We are aware that it takes energy to get an object, like a car or the package in Figure 7.4, up to speed, but it may be a bit surprising that kinetic energy is proportional to speed squared.
