# Homework Help: Acceleration - Displacement Graph

1. Jul 3, 2014

### PhysicsStudnt

In terms of calculus, How do i prove that the area under the acceleration time graph gives me the change in KE / mass.....

Attempt at solution....

Area under the graph of a function y = f(x) is given by ∫y dx

Therefore area under acceleration displacement graph is ∫a ds (considering the function to be a=f(s))

=> ∫f/m ds

=> 1/m (∫f.ds)

=> 1/m (W) .........[work done = ∫f.ds ]

=> ΔKE/m ........[W = ΔKE]

1. Is this proof correct mathematically and theoretically....
2. Is there a different or better proof...

It's not clear what you are trying to do. First, you talk about the area under the acceleration-time graph, then you talk about the area under the acceleration-displacement graph.

This is why PF has a HW template and we ask all HW posters to fill out the template when asking a question. It reduces the amount of confusion, which is always lurking to pounce on the unwary.
