release of energy in the form of heat, warming your hands, sparking a fire, and so on.[1] The greater the friction, the more energy released, so knowing how to increase the friction between moving parts in a mechanical system can potentially allow you to generate lots of heat!
Method One of Two:
Creating a More Frictive Surface

1
Create a “rougher” or more adhesive point of contact.When two materials slide or rub against each other, three things can happen: small nooks, crannies, and irregularities on the surfaces can catch on each other; one or both surfaces can deform in response to the motion; and, finally, the atoms within each surface can interact with each other.[2] For practical purposes, all three of these effects do the same thing: generate friction. Picking surfaces that are abrasive (like sandpaper), deform when pressed (like rubber), or have adhesive interactions with other surfaces (like tacky glue, etc.) is a straightforward way to increase friction.Engineering textbooks and similar resources can be great tools when picking which materials to use to generate high friction. Most standard building materials have known "friction coefficients" — that is, measures of how much friction they generate with other surfaces. Sliding friction coefficients for just a few common materials are listed below (higher coefficients indicate greater friction):Aluminum on aluminum: 0.34Wood on wood: 0.129Dry concrete on rubber: 0.6-0.85Wet concrete on rubber: 0.45-0.75Ice on ice: 0.01

Press the two surfaces together harder. One fundamental principle of basic physics is that the friction an object experiences is proportional to its normal force (for our purposes, this is basically the force with which it presses into the object it's sliding against).[3] This means that the friction between two surfaces can be increased if the surfaces are pressed into each other with greater force.If you've ever used a set of disc brakes (for instance, on a car or bike) you've observed this principle in action. In this case, pressing the brakes on a car pushes a set of friction-generating pads into metal discs attached to

Here is your answer...❤❤❤
To increase the amount of force that is being used simply increase the amount of pressure you apply when interacting with the body. To decrease friction, you can make the surface smoother, make the objects more streamlined, or reduce the forces acting on the surfaces.
I hope it's helps you plz mark me as brainliest❤❤❤
