and when you rub two objects together it will become warm or hot
Being counter-friction means to act in opposition or resistance to friction. It involves implementing measures or strategies to counteract the negative effects of friction, such as reducing resistance or increasing efficiency.
The effects of forces are materials can be either positive or negative. Positive effects include the ability to stop due to friction.

To reduce the negative effects of friction in systems, you can apply lubricants to surfaces in contact, use smooth surfaces or materials with low friction coefficients, and implement ball bearings or roller bearings to minimize direct contact between components. Additionally, ensuring proper maintenance and keeping surfaces clean can help reduce frictional resistance in systems.
some negative affects are hurricanes
there are some negative effects of later school start times:late finishfatiguelack of concentrationdon't get be out in the daylight as muchthey are just some of the negative effects, there are some more.
Australia ? You are a good example of what some of the negative effects are !

Friction can be negative or positive depending on the direction in which your measures are positive.
Grazing your knees and hands when falling over and sliding on a hard surface is caused by friction with the ground. A spacecraft returning to earth will heat up to red hot due to friction with the atmosphere. These are just two bad effects of friction. But, there are good effects, too. Friction from your vehicle or bicycle brakes will bring you to a stop! Friction from your tyres and the road surface will prevent you from skidding.
