Question

A force F1 = 10 (N) is displacing a 10 (kg) for 10 meters on a horizontal surface, while  a force F2 = 10 (N) is displacing a 10 (kg) for the same distance on an inclined plane making a 30 degrees with the horizontal plan. Is the work done by F1 less, equal or greater than the work done by F2? Explain  

A force F1 = 10 (N) is displacing a 10 (kg) for 10 meters on a horizontal surface, while a force F2 = 10 (N) is displacing a 10 (kg) for the same distance on an inclined plane making a 30 degrees with the horizontal plan. Is the work done by F1 less, equal or greater than the work done by F2? Explain

Explanation / Answer

W1 = 10*10 = 100J

W2 = 10*10*cos30 = 86.60J

the work done by F1 is greater than the work done by F2
