Work energy method and impulse momentum method

AI Thread Summary
The discussion clarifies that work and kinetic energy are distinct concepts, as are impulse and momentum. Work, defined as force applied over a distance, results in an increase in kinetic energy, but they are not identical. Similarly, impulse, which is force applied over time, leads to a change in momentum, yet impulse and momentum are also different. The conversation emphasizes the importance of understanding these distinctions in physics. Ultimately, recognizing the differences between these concepts is crucial for a comprehensive grasp of mechanics.

we have two concepts

1)if force is applied for a distance x(i.e work) it increases the kinetic energy of a mass

2)if force is applied for a time t(i.e impulse) it increases the momentum of the mass

why there are two concepts. Are the above two same?

Neither of those things you just said are correct. Work and kinetic energy are not the same thing and impulse and momentum are not the same thing either.
 

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'

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...
