  • What surface causes more friction: wood or glass?
    wood, less smooth
  • Why do swimmers wear tight suits?
    to reduce drag
  • Do astronauts experience friction in space?
    No because there are no atoms to act against motin
  • What happens to friction on wet roads?
    friction reduces
  • What can too much friction cause in machines (a type of energy)?
    overheating
  • What shape reduces friction in water?
    streamlined
  • Why do I put oil on my bike chain?
    to reduce friction
  • Which material has less friction: metal or rubber?
    metal, it is smoother
  • What sort of energy is often released by friction?
    heat energy
  • Why do athletes wear grip shoes?
    more friciton, or traction
  • What friction-related issue affects moving machines?
    wear and tear
  • What is the force again motion called
    Friction
  • Does ice have high friction have high friciton or low friction
    low friciton
  • what is frition in air and water called
    drag
  • Why is sand spread on icy roads?
    Increases grip
  • Over time Friction has an affect on tires which reduces their friction?
    The tread on the tire is reduced by friciton so friction becomes less
  • What are forces measured in?
    Newton's
