What did we learn last time ? energy kinetic energy potential energy energy transfer
Kinetic Energy Kinetic energy is motion energy What does the kinetic energy of an object depend on?
Which one has more kinetic energy? The blue car weighs 1 ton and is traveling 50 mph The truck weighs 2 tons and is traveling 50 mph
Which one has more kinetic energy? The blue car weighs 1 ton and is traveling 50 mph The racing car weighs 1 ton and is traveling 100 mph
Kinetic Energy KE = mv2 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
KE = mv2 How much more kinetic energy does the truck have compared to the car? 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
KE = mv2 How much more kinetic energy does the racing car have compared to the blue car? 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 What ways can potential energy be stored?
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 Where is the potential Where is the potential energy stored? energy stored? What is this called? What is this called? What are other examples of gravitational energy? What are other examples of gravitational energy?
Where is the potential energy stored? Where is the potential energy stored? What is this called? What is this called? What are other examples of What are other examples of elastic energy? elastic energy? Elastic Elastic Energy Energy Elastic energy is potential energy stored in the Elastic energy is potential energy stored in the stretching or compression of an object stretching or compression 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. Where is the potential energy stored? Where is the potential energy stored? What is this called? What is this called? 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!
What type of potential energy is stored? What type of potential energy is stored? Chemical Chemical Energy Energy Chemical energy is potential Chemical energy is potential energy stored in chemical bonds energy stored in chemical bonds..
Its all energy! kinetic gravitational elastic thermal chemical
