  • Walking down the street
    Kinetic Energy
  • Energy that is moving is ___________.
    Kinetic Energy
  • An archer with his bow drawn
    Potential Energy
  • The ball in position E has only kinetic energy, no potential energy. (TRUE or FALSE)
    FALSE The ball in position E has some potential and some kinetic energy.
  • A bowling ball rolling down the alley
    Kinetic Energy
  • The equation for weight is
    m x g
  • Explain the difference between potential and kinetic energy.
    Kinetic energy is energy in motion while potential energy is stored energy waiting to be used
  • W x h
    potential energy

    chemical potential
  • When riding a roller coaster, you go up and down many hills. As you get to the top of a roller coaster, what energy change is taking place?
    kinetic energy is changed into potential energy
