                                                                  Potential Energy
                Electric Energy
                energy carried by an                              Potential energy is stored energy due to the
                electric current                                  interaction between objects or particles.

                                                                  Objects have potential energy if they have the

               Let’s Begin

                                                                  Objects have gravitational potential energy if they
               Energy                                             have mass and height above Earth’s surface.

               Energy inf uences everything in your life, including
               the climate, the economy, and your body.











                                                                  • The bicycle and the football have the same height,
                                                                     but the bicycle has more gravitational potential
                                                                     energy because it has greater mass.

                                                                  • Although the basketballs have equal messes, the
                                                                     higher basketball has more gravitational
