friction is critically affected by your what?
quality of the Surface is affected to the Coefficient of friction
Friction can be a friend when walking and when driving a car. For example, walking or driving on ice can be very risky due to the lack of friction. Friction can be a foe when it causes more work to have to be done or excess heating. Friction is responsible for our getting blisters on our hands or feet.
Yes
Friction is a cause of lost energy and inefficiency. But it is critically important to have friction as regards automobiles. The most important use of friction by vehicles is that involving their contact with the ground. Without friction, there would be traction, which would translate into no acceleration and no control of the vehicle. Think this through and it will become clear.
a skydiver falling is affected by air friction or he would fall straight down in an instant
what are three things affected by friction
No.
quality of the Surface is affected to the Coefficient of friction
Roller Coasters. roller coasters are affected by rolling friction (hence roller) not sliding
They heat up.

Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
