Friction

AI Thread Summary

The force of friction acting on an object in constant motion equals the applied force, resulting in zero net force, as stated by Newton's Second Law. This law indicates that when an object maintains constant velocity, there is no acceleration, and thus all forces acting on it are balanced. The discussion clarifies that friction opposes the applied force, leading to equilibrium in motion. Understanding this relationship is essential for applying Newton's laws effectively. Overall, friction and applied force are equal when an object moves at a constant speed.

Does the force of Friction acting on an object equal the applied force on an object if it is in constant motion?

Is that one of Newton's Law's? Which?

Thank you

Newton's 2nd law tells you that if an object has constant velocity (thus zero acceleration), then the net force on it must be zero.

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
