Friction generates HEAT. Heat can burn you. Rub your left arm with your right arm using a lot of pressure. It will get uncomfortably hot very quickly!
An air hockey table with the air turned on has almost no friction. Other than that, very smooth surfaces cause very little friction. If you use certain types of cleaner on hardwood floor, it can be turned into a surface with little or no friction (and you will fall an hurt yourself a lot. not suggested.)
Friction can cause injuries by generating heat when two surfaces rub against each other, leading to burns or blisters. It can also result in skin abrasions or blisters from repeated rubbing or chafing. Additionally, friction can make it harder to slide or move objects smoothly, leading to strain or sprains on muscles and joints.
harmful friction is when friction can do harm or be a problem for example of this is if your skiing down a hill with grass you will have to much friction then you fall and get hurt :p
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when two surfaces are in motion relative to each other.
Three types of friction are : 1. Kinetic friction :Friction that arises between surfaces in relative motion. 2. Static friction :Friction that acts between surfaces at rest with respect to each other 3. Rolling friction : Friction that occurs when an object rolls over a surface. Static, sliding, rolling.
it can hurt them because what if they were to fall they would get hurt and it would hurt more if they were on the top of a pyramid.
because you are using friction or fire
because of the friction created between the t-shirt and the nipples....
Think of a car, friction causes air resistance on the car and results in lower gas mileage, but without friction, the tires would just spin in place and the car would not go anywhere.
The vibrations of the throat cause friction and damage cells.
Well, if they were light or had nothing in them it wouldn't hurt but if it was full gravity would bring it to your head causing friction and pain.
The reason the back of your hand hurts after playing soccer is because of the friction.
Your fingers hurt from playing the guitar because pressing down on the strings for an extended period of time can cause pressure and friction on your fingertips, leading to discomfort and pain.
Your fingers hurt from playing guitar because the strings put pressure on the fingertips, causing friction and strain on the skin and muscles. Over time, this can lead to soreness and discomfort.
When playing the guitar, your fingertips may hurt because the strings put pressure on them, causing friction and irritation. Over time, calluses will form on your fingertips, reducing the pain.
It may, under certain circumstances. For example, if you brake suddenly, the tyres might wear off quickly.
Probably just friction, but if more than a week has passed and it still hurts, then get a blood test.
