I'm taking a driving course and one of my chapters is about driving and laws of nature. One of my questions asks for effects of kinetic energy. Can anyone help?

for lower speeds, i.e. not near speed of light
ke = 1/2 m v^2
So doubling speed = quadruple energy.
Additionally drag is also proportional to the square of velocity so that the amount of power necessary to push a car is proportional to the cube of the velocity.

If I save in ideas wisely, friction supplies you negative acceleration contained in the option route. It ought to substitute kinetic ability because it alterations speed. Does this answer your question?
