what is an easy way to remember the equations used for: kinetic energy, potential energy, work, and power?

  • lab science 9th grade - ,

    Keep doing problems that use these concepts. You will remember them before too long.

    KE = (1/2) M V^2
    Power = Work/Time
    Work = Force*distance , where the force is the component along the direction of motion.

    Remember that there are various kinds of potential energy. It equals the work done against an external force in moving from point A to point B. Only the change of potential energy is important. The zero point of potential energy can be arbitrarily defined.
