Work Energy And Power Worksheet With Answers
Work Energy And Power Worksheet With Answers - The amount of energy transferred depends on the power of the appliance and how long it is switched on for. Calculate the work done on the bicycle. Work done = 7,500 j. Work done= 𝑑 the unit of work done is in joules (j), which is equivalent to newton. Why are both energy and work measured in joules? The body losing energy does work, the body gaining energy has work done on it. Web power is a way to describe how quickly energy is transferred from one store to another or one object to another. This is tailored for the ocr a specification, however, the versatile nature of this resource makes it suitable for other exam boards too. A ball with a weight of 30 newtons is kicked 2 metres into the air. Web power is the energy transferred per unit time, therefore to find the value of time taken we must divide the energy required by the power.
Determine the work (in joules) done upon the backpack. The body losing energy does work, the body gaining energy has work done on it.
