5+Mechanical+Systems

Machines are used for many purposes in our daily lives when we need to transfer energy into motion or move materials in a controlled way. 

Focusing Questions: How is energy transferred in mechanical devices? How do mechanical devices provide for controlled application of energy in ways that are efficient, effective and responsible?
