Exploring Energy Kinetic and Potential
What did we learn last time ? energy kinetic energy potential energy energy transfer
Kinetic Energy Kinetic energy is motion energy The kinetic energy of an object depends on both its mass and its speed. 10 kg
Kinetic Kinetic Energy Energy Kinetic Kinetic e energy changes with the mass of nergy changes with the mass of an object an object Kinetic Kinetic e energy changes with the speed of nergy changes with the speed of an object squared an object squared The blue car weighs 1 ton and is traveling 50 mph The truck weighs 2 tons and is traveling 50 mph The truck has _____ times kinetic energy as the blue car. 2
Kinetic Kinetic Energy Energy Kinetic energy changes with the mass of Kinetic energy changes with the mass of an object an object Kinetic energy changes with the speed of Kinetic energy changes with the speed of an object squared an object squared The blue car weighs 1 ton and is traveling 50 mph The racing car weighs 1 ton and is traveling 100 mph The racing car has ___ times kinetic energy as the blue car. 4
Potential Energy Potential energy is stored energy Potential energy can be stored in many ways
Gravitational energy is Gravitational energy is potential energy stored in an potential energy stored in an object s height object s height.. Gravitational Gravitational Energy Energy
Chemical Chemical e energy is potential nergy is potential energy stored in chemical energy stored in chemical bonds bonds.. Chemical Chemical Energy Energy
Elastic Elastic Energy Energy Elastic energy is potential energy Elastic energy is potential energy stored in the stretching or compression stored in the stretching or compression of an object of an object..
Thermal Thermal Energy Energy Thermal energy is stored in Thermal energy is stored in an object s temperature. an object s temperature. At a large scale it looks like At a large scale it looks like potential energy, but on a small potential energy, but on a small scale it looks more like kinetic scale it looks more like kinetic energy. energy. We ll talk more about that later! We ll talk more about that later!
Its all energy! kinetic gravitational chemical elastic thermal
