Presentation transcript:

Group Members First Names Simple Machine Name Group Members First Names

Work Explain how your machine changes the size of a force needed, the direction of a force, or the distance over which a force acts

Power Input and output time is the same, so show how increased work in the output results in increased power

Work and Machines Summarize how your machine works by applying the vocabulary terms to your machine (input force, input distance, work input, output force, output distance, work output)

Mechanical Advantage Explain mechanical advantage using the input and output force for your machine Explain how friction reduces the AMA of your machine

Efficiency Use real-life examples to explain the efficiency of different applications of your machine
