Gravitational Work: Ball & Earth Interaction Analysis

AI Thread Summary
When a ball falls a distance (h), gravitational potential energy converts to kinetic energy, resulting in no net change in total energy. Gravity performs positive work on the ball, and this interaction can be viewed through Newton's third law, where the ball also exerts gravitational work on the Earth. Analyzing only the ball is insufficient; the energy transfer between the ball and Earth must be considered. Gravitational potential is a property of the entire system rather than just the ball. This understanding emphasizes the interconnectedness of energy interactions in gravitational scenarios.

If an object (a ball) begins at rest and falls a distance (h) there is a transformation of gravitational potential energy into kinetic energy (the ball is moving at time-final for my analysis), resulting in a zero net change of total energy for this ball. But, gravity was doing positive work over the distance h. Is it correct to view this scenario as an expression of Newton's third law of motion in that the ball also does gravitational work on the Earth; hence, the work of the ball on the Earth cancels the work of the Earth on the ball. It is insufficient to only analyze the ball. In terms of energy, you must recognize the interaction (transfer of energy) of the two objects. Is my thinking accurate?

Gravitational potential is a property of the whole system (ball plus earth). It is not a property of an object, although that is a good approximation if you have a ball and Earth (as the displacement of Earth is negligible while the force is the same).
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
