Potential and Kinetic Energy © The Science Duo  Potential Energy Stored energy or energy of position Gravitational Potential - an object gains more potential energy as its height or mass increases Elastic Potential – energy stored in bending, twisting, or stretching of an object A rollercoaster at the top of a hill has more potential than at the bottom A rubber band A clock hanging on Energy stored stretched back the wall within food Forms of Potential Energy Gravitational Elastic Magnetic Chemical Electrostatic Nuclear  Kinetic Energy Energy of motion An object gains more kinetic energy as its speed or mass increases Greater speed = greater kinetic energy Greater mass = greater kinetic energy A rollercoaster at the bottom of the tallest hill moving its fastest A moving ball A speeding car Flowing water  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? 1.
