Question
IP Calculate the work done by gravity as a 5.6kg object is moved from A to B in the figure(Figure 1) along paths 1 and 2.
Enter your answers numerically separated by commas. Express your answers using two significant figures.
W1, W2 = ______ J
How do your results depend on the mass of the block? Specifically, if you increase the mass, does the work done by gravity increase, decrease, or stay the same?
- Increase, Decrease, or stays the same.

Specifically, if you increase the mass, does the work done by gravity increase, decrease, or stay the same? - Increase, Decrease, or stays the same.Explanation / Answer
a)
In path 1
Work done in horizontla directon is zero .so Net work done along path 1
W1=mgh =5.6*1*9.8
W1=54.88 J=55 J(approx)
In path 2
Net work done along path 2 is
W2=55 J
b)
Increases ,since work done is directly proportional to mass.
