Identification should include
- defining and using terms force, pressure, and buoyancy
- explaining that force is caused by contact between solids, friction, fluids and gases
- demonstrating the application of force in engineered systems in two or more fundamentally different ways.
Process/Skill Questions:
- What are some innovative ways to demonstrate the application of force?
- What resources are available to investigate the application of force?
- How can fluids be used to multiply force?
- How is air pressure used to fly a plane?
- What everyday items would not work if there was no friction?
