Storyboard Text

  • What Is Friction? Friction is the rubbing of one object against another.
  • Does Friction Help You? Yes, it helps us maintain our stability and prevents us from slipping. 
  • Why Does Friction Heat Things Up? The two atoms in the surfaces that are rubbing together store potential energy, when they move away from each other the energy becomes kinetic.
  •  Can Friction Cause Fires? Yes, friction causes some of the energy of motion to be converted into heat. That is why when you rub two sticks together it makes fire.
  • Why Is It Important To Have Friction? Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. 
  • What Does Friction Do In Nature? Coefficients of friction range from near zero to greater than one. For surfaces in relative motion, where is the coefficient of kinetic friction. The Coulomb friction is equal to, and the frictional force on each surface is exerted in the direction opposite to its motion relative to the other surface.
