Q: How can I write the vector form of this equation, a = vdv/dx?

Juhi KumariMy Physics teacher was deriving the 'Work-Energy Theorem' for a single particle in the class; where after doing the vector addition of all the forces acting on the particle, he put the resultant of all those forces equal to the product of mass and acceleration of the particle, which was totally c...

Q: How often should someone run to maintain ability?

PiperI spent my summer running a lot more than I had in the past, getting up to distances of 7 miles. I am not a fast runner and it took quite a while to get myself to get to the point where I could run over 2.5 miles. Let it be clear, I am still not fast, averaging 10:30-12:30/mi depending on the dis...

The other definition that I generally use is $\displaystyle CS(p_0) = \int_{0}^{q_0} [p(q) - p_0] \ dq$. Are the two definitions same? I tried e...

Q: Is force really considered a push or a pull?

Steven GrullonIf an object is pushed/pulled at a constant velocity and it doesn't accelerate, is there a net force still being applied to the object? A force is a push/pull so there must be a force, despite there being no acceleration, right?
