Potential energy is stored energy. Potential energy is associated with an object that has the potential to move because of its position relative to some other location. Unlike kinetic energy, potential energy depends not only on the properties of an object but also on the object's interaction with i

    1. POTENTIAL ENERGY

    2. Potential energy is stored energy Potential energy is associated with an object that has the potential to move because of its position relative to some other location. Unlike kinetic energy, potential energy depends not only on the properties of an object but also on the objects interaction with its environment.

    3. Gravitational Potential Energy The energy associated with an object due to the objects position relative to a gravitational source is called gravitational potential energy

    4. Elastic Potential Energy The energy available for use when a deformed elastic object returns to its original configuration is named elastic potential energy.

    6. P R O B L E M A spring with a force constant of 5.2 N/m has a relaxed length of 2.45 m. When a mass is attached to the end of the spring and allowed to come to rest, the vertical length of the spring is 3.57 m. Calculate the elastic potential energy stored in the spring.

    7. Work-Potential Energy Theorem Work done on an object by the gravitational force as it falls along vertical distance;

    8. Mechanical Energy The sum of kinetic energy and all forms of potential energy is called mechanical energy.

    9. P R O B L E M Starting from rest, a child zooms down a frictionless slide from an initial height of 3 m. What is her speed at the bottom of the slide? Assume she has a mass of 25 kg.
