RED What is the formula for Gravitational Potential Energy? (GPE) GPE=wh or g(m)h What is energy efficiency? Energy efficiency is the ratio of input energy to useful output energy. What is the difference between energy conversion and energy transfer? Energy conversion is the changing from one form to another. Energy transfer is the moving from one object to another. What is fusion? The combining of atomic nuclei What is fission? The splitting of an atomic nucleus What type of energy relates to fission and fusion and how the identity of the atom changes? NUCLEAR

PURPLE What is the formula for Kinetic Energy? (KE) KE=1/2mv2 What is the by product of all energy conversions? Thermal Energy What is the Law of Conservation of Energy? Energy cannot be created or destroyed only transferred or transformed. Why can you not have perpetual motion? Some energy is always transferred to thermal through friction What is the definition of friction? A force that opposes motion when objects are in contact. What is the definition of energy? The ability to do work

A C B ORANGE Where is the most Kinetic Energy? B Where is the most Potential Energy? A What are the different types of energy represented above? Potential and kinetic What two factors determine Gravitational Potential Energy? (GPE) weight and height What are the two factors that determine Kinetic Energy? (KE) mass and velocity Which factor has the most impact on kinetic energy? velocity

BLUE Show the energy conversions for the following scenarios. When a student uses a rubber band to fire a hornet. ElasticKinetic and Thermal When a star joins two atoms to form a larger atom and light. NuclearLight and Thermal When your battery powered Bluetooth speaker is playing music. ChemicalElectricallight, sound, and thermal A solar panel heating water. Come up with your own daily experience and describe the transformation of energy.

YELLOW Rank the following in order from greatest amount of kinetic energy to the least. Assume the motorcycle is double the mass of the tricycle. a. A tricycle traveling 2 m/s 4 b. A tricycle traveling 4 m/s 2 c. A motorcycle traveling 4 m/s 1 d. A motorcycle traveling 2m/s 3 What is kinetic energy? Energy of motion What is gravitational potential energy? Energy that overcomes the force of gravity What is mechanical energy? The energy based on the position and motion of an object. What is the formula for mechanical energy? KE + PE Two skiers are at the top of a hill with 500J of GPE. Paul generated 50J of thermal energy through friction and Ashley generated 100J. Which skier was more energy efficient? Why? Paul because he transferred more useful energy.

Pink Station What kind of energy does not need matter, but does travel in waves? LIGHT or Radiant What kind of energy comes in the form of moving electrons? Electrical What kind of energy is due to the random motion of particles that make up an object? Thermal What kind of energy is formed from the arrangement of atoms? CHEMICAL What kind of energy is stored when something is stretched? ELASTIC What kind of energy needs matter, and travels in waves? SOUND What kind of energy do you give to an object when you use a force that goes against the force of gravity? Gravitational Potential

GREEN Math Station Determine the weight of a skateboarder with a mass of 40kg. 392 N What is the gravitational potential energy of that skateboarder at the top of a 5m half pipe? 1960 J What would be the kinetic energy of the skateboarder if he is going 10m/s at the bottom of the half pipe? 2000J What is the mechanical energy of the skateboarder at the mid point of the half pipe (2.5m) if he is going 6m/s? KE= 720J GPE=980J ME= 1700J
