Ball bearings, oil, lubricant. Pretty much anything that reduces the friction between two interacting surfaces.

3 ways of decreasing friction in shoes is to put in shoe cookies (shoe pads), bandaids, or stuff them with toilet paper.
by increasing smothness wecan decrease the friction and vice versa

Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.

You can minimise friction by Decreasing surface area, making area smoother, lubricating it(eg. car parts) and the opposite to maximise friction.
