There are several types of friction that influence spin of the ball in tennis. The sliding friction between the ball and the strings, the static friction between the ball and the strings at the grip phase, the static friction between the main and the cross strings, and the sliding friction between the strings.
When our bodies (shoes) make contact with the tennis court. We apply a force to that surface.
friction heat up you socks and cause slintters
Friction helps players to walk and run,it reduces the speed of the ball,without it we would not be able to hold the raquet
maybe friction cause it makes your shoes torn out sometimes
When a spaceship enters atmosphere it can catch fire due to heat produced by friction with air.
yes friction is supporting
1. The soles of your socks wearing out 2. The gears in you care will wear down if not lubricated with oil 3. Holes in your jeans 4. Scraping your knee Harmful friction consists of two surfaces in motion, yet not in harmony with each other or one surface in motion against a fixed surface, which causes a wearing of one or both surfaces. Examples of harmful friction would be an abrasion to the skin from a person sliding on a rug or friction between a foot and a shoe creating heat and a blister in the skin of the foot. This is wrong. DONT USE THIS INFORMATION There are many examples of harmful friction. This can include the scrapes and cuts your encounter when falling down on the sidewalk. This can also be found in engines that are not properly lubricated causing them to heat up and malfunction.
friction can be harmful because if you stick 2 objects to rub against eachother for to long it will explode
No, the gas is not harmful.
Bowling, curling, and tennis
friction
examples of harmful liquids
Friction can be harmful or helpful when driving, no matter what time of year. For instance it is helpful when breaking and it is harmful between bearing surfaces. The loss of friction between the tyres and the road during winter can be disastrous.
