Explanation and Examples
let the mass of the compressor be
mass (m):
height in x axis is (h1)
height in y axis be (h2):
Height difference: h2-h1
displacement x force:
mass x gravity x height
(m)*9.8*(height difference) = ___ J
Since gravity is forcing down, it would be negative!
Put the values that you require and get the answer.
Answer:
W = mg × (r₂ - r₁)
Explanation:
Work done is the product of force acting and the displacement. In this case, we have to find the work done by the gravity on the compressor during displacement.
Let r₁ and r₂ are the initial and the final position of the body. So, displacement will be, r₂ - r₁.
Work done, W = F × d
Since, F = mg
W = mg × (r₂ - r₁)
Hence, the work done by the gravity on the compressor is " mg × (r₂ - r₁) Joules".
