Assumptions in two balls falling experiment
A typical undergraduate physics class problem to demonstrate the effects of conservation of momentum is to have two balls of different mass falling one above the other (the largest mass below) to the …

Tension in massless string
In a massless string the sum of forces acting on every part of the string must be zero, otherwise, if the force was finite, the string would get an infinite accelleration $a = \lim_{m\rightarrow 0} F/ …

What does it mean to say work is path-independent when pushing an object in different direct...
The work-energy theorem states that the total work done on a particle is equal to the change in kinetic energy.
You are doing the same amount of work in either case, but gravity is doing different wo …
