In our daily lives, a lot of works are applied and used. We can use it wisely by using equipment such as pulley. Through the simulation of pulley, we could see that the work applied in to the pulley by inclining to heavier side of pulley. Pulley can make works easier because humans don’t need to use their own work to lift things up and move. Hanging heavier object on the lope and hang the lighter one on the other side of pulley and wire them to the circular thing. Also when you push the lawn mowers, work applies in to it. Equation of work is
W = F x (cos ) x d
W is work, F is force that applied and d is distance that the subject moved. …show more content…
The answer would be 1838.5.
Hypothesis
We can predict that more mass that you work on makes more work to do which means when mass increases, work increases too. In this lab, the mass of shoe is twice heavier than the mass of calculator. Therefore we can guess the difference of work because in the calculating procedure, height which is 0.9m and the gravity which is 9.81 apply same to both of mass. Adding, subtracting, multiplying and dividing of both factors in each side make same ratio but different results. …show more content…
| Mass | Force | Height(d) | Work | Calculator | 0.105kg | 1.03N | 0.9m | 0.927J | Shoe | 0.210kg | 2.06N | 0.9m | 1.854J |
According to the graph and a chart, I can confirm that my hypothesis was right. The work of shoe is twice higher than the work of calculator because the mass of calculator is twice less than the mass of shoe. Work equation which is W = F x d. This equation doesn’t change the result of mass because you multiply the gravity to mass to get the force(F), multiply the height(d) which is measured in same place so make same result to both sides.
Discussion
This lab was about work by lifting 2 objects and compares the result of them.
W = F x d Using this equation to calculate the works don’t make the difference of ratio between 2 objects because that applies to both of factors which means they will have different results but same ratio. Works are always applied to our daily lives. For example, when you lift the dumbbell, you use your biceps to move them and those movements make works.
