it takes less energy to stop a small vehicle compared to a large vehicle because there is less energy or force behind the vehicle making it go. thus the stopping distance is shorter for a smaller vehicle than a larger vehicle, assuming they were originally moving the same speed.
Kinetic energy is energy in motion- Potential energy is energy not in motion- If u have a ball and u bounce it, and you let it keep bouncing, the ball will not go as high as it did the first time
