Describe Kinetic Energy

Describe the relationship between KE and PE

KINETIC ENERGY

Kinetic Energy: The energy of an object that is due to the object’s motion or action.

MAXIMUM KINETIC ENERGY

Maximum Kinetic Energy- When the motion or action of the object is at its greatest.

MINIMUM KINETIC ENERGY

Minimum Kinetic Energy- When the motion or action of the system is at its least.

PENDULUM LAB

Scientific Question: How are kinetic and potential energy related?

Safety precautions: Use the pendulum only as demonstrated in class. Keep all yard sticks on the tables.

PE/KE RELATIONSHIP

How are PE and KE related?When is PE at its max?When is KE at its max?When are PE and KE equal?

PE/KE RELATIONSHIP

PE and KE have an INVERSE relationship.As one goes up, the other goes down.

PRACTICE PROBLEM

ROLLER COASTER LAB

Goals: SI: Record observations correctly Energy: Analyze the amount of kinetic and

potential energy in a system. Question

How does the amount of potential energy in a system effect the amount of kinetic energy in a system?

Safety Precautions Marbles are to stay on the tracks only. Do not stand on chairs or tables. Keep tracks out of the isle.
