PSc.3.1.4 Infer the work and power relationship:
- Determine the component simple machines present in complex machines – categorize a wedge and screw as variations of an inclined plane; a pulley and wheel & axle as variations of a lever.
- Explain the relationship between work input and work output for simple machines using the law of conservation of energy.
- Define and determine ideal and actual mechanical advantage: E R d IMA d R E F AMA F Define and determine efficiency of machines: 100 out in W Efficiency x W
- Explain why no machine can be 100% efficient
