I use this 25 slide Power Point over a 2 week period to teach a unit on Force. It has many interactive slides that demonstrate what a force is. If you have a SmartBoard, you can have your students interact with the Power Point directly. However, if you do not have a Smart Board, you can control the animation from your computer.
The concepts covered are as follows:
* Force - what is a force?
* Unit of Measurement - newton versus pound
* Force Vectors - how to measure force
* Balanced/Unbalanced Forces
* Mass versus Weight
* Gravity - equation w=mg (also includes practice problem w/ solution)
