PS.6 - Types of Energy

The student will investigate and understand forms of energy and how energy is transferred and transformed. Key concepts include

a) potential and kinetic energy; and

b) mechanical, chemical, electrical, thermal, radiant and nuclear energy. 


Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • Energy can be transferred between objects or can be converted into different forms.
  • Energy exists in many forms and has the ability to do work or cause a change.

  • I can explain how a roller coaster continues moving.
  • I can explain how food gives me energy.

UNDERSTANDING THE STANDARD

  • Energy is the ability to do work.
  • Energy exists in two states. Potential energy is stored energy based on position or chemical composition. Kinetic energy is energy of motion. Students should know that the amount of potential energy associated with an object depends on its position. The amount of kinetic energy depends on the mass and velocity of the moving object.
  • Important forms of energy include radiant, thermal, chemical, electrical, mechanical, and nuclear energy. Visible light is a form of radiant energy and sound is a form of mechanical energy.
  • Energy can be transformed from one type to another. In any energy conversion, some of the energy is lost to the environment as thermal energy.

ESSENTIALS

In order to meet this standard, it is expected that students will

a)  differentiate between potential and kinetic energy.

     use diagrams or concrete examples to compare relative amounts of potential and kinetic energy.

b)  identify and give examples of common forms of energy.

     design an investigation or create a diagram to illustrate energy transformations. 


KEY VOCABULARY
