In this lab, we use electrical meters to calculate our average home's power usage
Question:
1.If you ran up the ramp in half the time of another student of equal weight you did the same work but used twice the power. Explain. This is because p=w/t. The smaller number "t" is the bigger number power is.
2. If the height were reduced by half, the work would be less but the power would be the same
3.Greater power is not necessary, it uses the same amount of power.
4. 66 gallons
5. .134 hp for the light bulb. 150 kW for the engine
