    Undergrad Why doesn't mass of a pendulum effect its time period

    I'll jump straight to my query. If PE = mgh, and if the "m" is increased, the PE shall also increase. Neglecting friction, Total mechanical energy(TME) = PE + KE. Since PE increases, the total mechanical energy of the system shall also increase. At its equilibrium position, where PE = 0...

    Undergrad Plotting the graph of pendulum period versus length

    why do we square the value of T ( time period) while plotting the graph of effect on time period of a pendulum with change in its effective length ? also while deriving the formula of T=2∏√(l/g) why do we take T^2 = 1/g. Whats the need for squaring the time period ?

    High School Pi Day Misconception: Is Pi an Irrational Number?

    Happy Pi day folks ! Heres a general misconception I am having. It might turn out to be a pretty easy question so please do help me. If i pull out my compass to a radius of 7 cm and draw a circle on a paper. Then i'll take a piece of thread and cut it such that it matches exactly with the...
