Friction- A force that acts upon objects to resist change in motion.
If you try to push a car up a slick, icy hill, it will be easier than trying to push the same truck up a dirt road with lots of gravel. Why? Because the dirt and gravel rub against the tires to help the truck resist motion.

What is an example of fluid friction?
example of fluid friction are air resistance or drag because an object moving through air actually collides with miniature particles, specially dust particles .
An example of fluid friction?
An airplane flying through the air, a swimmer diving into a pool etc.
What is the mathematical equation for friction?
An important formula is that friction = (coefficient of friction) x (normal force).
How is friction good and bad?
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
How does friction affect shoes?
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
