1 Work and Power Launch Lab You will complete the launch lab on page 87. BUT!! We will have a few exceptions. – First you are required to have 5 different weights (meaning go from a smaller book and then increase the weight from there) – Second you are required to measure the distance using a meter stick. You will need 5 different distances. – Your table will look as follows…AND don’t forget to answer the 2 follow up questions TODAY titled “Think about this” How many BooksForce (N)Distance (meters) WorkPower 1NmWork andpower 2Nmwill befilled in 3Nmlater 4Nm 5Nm

2 Work

3 Is this work?! Calculate the work done when a force of 1 N moves a book 2 m. Calculate the work done when a 20-N force pushes a cart 3.5 m. Calculate the work done in lifting a 500-N barbell 2.2 m above the floor.

4 Power

5 Power up! Calculate the watts of power expended when a force of 2 N moves a book 2 m in a time interval of 1 s. Calculate the power expended when a 20-N force pushes a cart 3.5 m in a time of 0.5 s. Calculate the power expended when a 500-N barbell is lifted 2.2 m in 2 s.

6 W and P Practice 1.How much work is done when an 8 N force moves a block 7m? 2.Eva applies 40N force to move her bookcase 3m, how much work did Eva do? 3.How far will 490 J of work raise a block weighing 7 N? 4.Sheila did 110 J of work to move a chair 2 m to the right. How much force did Sheila use to move the chair? 5.Which is more work, pushing with 115 N over 15m or lifting 20N over 10 m? 6.How much power does it take to do 500 J of work in 10 sec? 7.How much power does it take to lift 250 N, 40 m high in 2 seconds? 8.If it takes 20 N to move a box, how much power will be needed to move the box a distance of 5 meters in 5 seconds?
