    Undergrad Why is the work done by an ideal gas the area under a PV diagram?

    Well yes, I know that the equation is true, but I was wondering why it's physically true. For example, the area under a velocity-time graph is displacement. Why is the area under the graph the work done?

    Undergrad Why is the work done by an ideal gas the area under a PV diagram?

    Could someone please prove why the work done by a gas is the area under a PV diagram? That is, I know that dW=P \text{ }dV, but why is that true physically? I realize that W=f \cdot d \text{ and } F=P \cdot A .Thanks.

    Undergrad How to prove Theta for a incline plane.

    If you draw down the lines for force from the point where the box touches the ramp, everything becomes much clearer. Two right angles are created: one at the flat base of the ramp and one at the point where the box touches the ramp. The triangle with the original θ is completed by an angle with...
