Potential & Kinetic Energy Notes

Potential Energy Stored energy or energy of positionGravitational Potential - an object gains more potential energy as its height or mass increasesElastic Potential – energy stored in bending, twisting, or stretching of an objectA rollercoaster at the top of a hill has more potential than at the bottom Forms of Potential Energy gravitational elastic magnetic chemical electrostatic nuclear Kinetic Energy Energy of motionAn object gains more kinetic energy as its speed or mass increasesGreater speed = greater kinetic; Greater mass = greater kineticA rollercoaster at the bottom of the tallest hill moving its fastest Forms of Kinetic Energy mechanical electrical thermal electromagnetic sound Potential vs. Kinetic Rollercoaster As potential energy increases, kinetic energy decreases and vice versa. greatest potential energy least kinetic energy equal amount of potential and kinetic energy greatest kinetic energy least potential energy Potential or Kinetic? Potential A skier at the top of a mountain A boulder at the top of a cliff A compressed spring A catapult ready to launch an object Kinetic The movement of wind during a storm Swinging a hammer toward a nail A sprinter running a race A pencil falling off a desk
