Presentation transcript:

Energy Kinetic energy is the energy of motion. Potential pnergy is stored energy.

Energy - What Is Energy? Kinetic Energy Kinetic energy increases as mass and velocity increases.

Energy - What Is Energy? Potential Energy Gravitational potential energy increases as weight and height increase.

Energy Calculating Mechanical Energy About 1000 J Reading Graphs: According to the graph, how much kinetic energy does the diver have at 8 m? - Forms of Energy

Energy Calculating Mechanical Energy Kinetic energy = about 2000 J; potential energy = about 3000 J Calculating: Using the graph, find the kinetic energy of the diver at 6 m. Then calculate the diver’s potential energy at that point. - Forms of Energy

Energy - Energy Transformations and Conservation Energy Transformations Most forms of energy can be transformed into other forms.

Energy - Energy Transformations and Conservation Transformations Between Potential and Kinetic Energy A pendulum continuously transforms energy from kinetic to potential energy and back.
