Kinetic and Potential Energy!

Where is potential energy the lowest/highest and where is kinetic energy the lowest/highest?

Big idea!

There are different types of potential energy.

I can ...

• investigate to determine how height and mass of an object affect gravitational potential energy.

    · experiment with an object to change its elastic potential            energy.

   ·  experiment with the different types of potential energy               (gravitational potential, elastic potential, chemical                      potential, electrical potential and magnetic potential) to            explore the relationship of energy transfer and springs,              magnets or static electricity.

     ·  describe the different types of potential energy.

      ·  recognize that rearranging atoms into new positions to              form new substances (chemical reaction) is evidence that           the chemical potential energy has most likely changed.

Vocabulary:

chemical potential energy  
elastic potential energy
gravitational potential energy
magnetic potential energy
potential energy
chemical reaction
electrical potential energy

Energy is the ability to do work!  There are 2 types of energy: kinetic and potential.  Kinetic energy is the energy of motion and potential energy is the energy that is stored and ready to do work.  


Study the chart above - can you relate each type of potential and kinetic energy to its source?

Question 1:  Now match each of the following images to its type of potential energy.  

Example 1 - Sponge Bob and Patrick are falling off the cliff


Example 2



Example 3

Example 4


Example 5

Example 6


Example 7


Example 8


Question 2 - Where in these wrecking ball examples would be the potential energy the highest and the kinetic energy the highest?
