  • friction opposes the force that you exert when you push or pull an object
  • friction can control movement, increase with the mass of an object and produce heat
  • what are the three facts about friction?
    it can control movement, increase with the mass of an object and produce heat
  • the three types of friction are surface friction, water resistance, and air resistance
  • what are the three types of friction?
    surface friction, water resistance and air resistance
  • treads, spikes, and rubber or rough materials increases friction
  • asphalt, rollers and wheels, lubricants help in decreasing friction
  • energy is what gives us the ability to do work
  • the two major types of energy are potential and kinetic energy
  • energy comes in different forms which are mechanical, electrical, radiant/light, chemical, sound, and thermal energy
  • energy transformation is the change of energy from one form to another.
  • the law of energy conservation states that energy changes forms meaning it cannot be destroyed nor created and that the amount of energy remains the same.
  • what law states that energy cannot be created nor destroyed?
    law of energy conservation
