Strand 8.2: ENERGY IS STORED AND TRANSFERRED IN PHYSICAL SYSTEMS

Objects can store and transfer energy within systems. Energy can be transferred between objects, which involves changes in the object's energy. There is a direct relationship between an object's energy, mass, and velocity. Energy can travel in waves and may be harnessed to transmit information.

Standard 8.2.1

Use computational thinking to analyze data about the relationship between the mass and speed of objects to the relative amount of kinetic energy of the objects. Emphasis should be on the quantity of mass and relative speed to the observable effects of the kinetic energy. Examples could include a full cart vs. an empty cart or rolling spheres with different masses down a ramp to measure the effects on stationary masses. Calculations of kinetic and potential energy will be learned at the high school level. (PS3.A, PS3.C)

• SEEd Storyline 8.2.1-3
  Storyline Big Ideas: Speed and Mass affect the amount of kinetic energy an object has. Which would do more damage in a crash, a semi truck or a smart car?
