Let's take a look at the elevator and the person standing on it from an inertial frame of reference, the ground frame. Now, If you draw the free body diagram for the person in the elevator (which is ...

but I cannot do the same problem about any random point by applying the first equation that I mentioned ,why is this happening ? Because $\displaystyle{\vec{\tau} =\frac{d\vec{L}}{dt} = \frac{d(I\vec{... View answer 1 votes As far as I know in an RC circuit i.e. one consisting of both resistors and capacitors. The charge in the capacitor can be expressed as a function of time as : $$\displaystyle{q(t) =CV(1-e^{\frac{-t}{\... View answer 1 votes First lets be on the same page regarding what is angular velocity ? Angular velocity often, denoted as \omega is the rate of angular displacement, denoted as \theta with respect to time i.e. you ... View answer 1 votes Can work done by Kinetic Friction on an object be positive? Zero? Yes it can be either positive or negative or zero for an object. But always negative for a system. Can Static Friction do Non-zero ... View answer 0 votes It doesn't really do anything...when you show a resistor in a circuit you are actually representing the resistance to the flow of current of your load i.e. some device that would be connected like say ...

The time period for a simple pendulum is independent of its initial conditions.$$T = 2\pi\sqrt{\frac{l}{g}}$$where$...

@Semoi's graph is correct for plotting velocity versus time. Acceleration is the change in velocity. Many a times like when in uniform circular motion the speed remains constant but due to the change ...

Suppose i have a point mass which is moving in a circular path Let the mass of the particle be $m$ If we see this particle from a frame of reference located not at the centre of the circle but say ...
