Hi everyone, I'm new to this sight/forum so I apologies in advance if I've got the wrong platform or have made any other faux par.
This is probably very elementary to most on this forum; can someone please tell me and hopefully explain a few things around transfer of energy in pendulums. Here is what I am pondering...
Is the energy required to raise a pendulum bob to its point of maximum potential energy more, less or equal to the energy then seen in the movement of the bob back and forth through the resulting oscillations? - I realize that the exact measurements of this depends on the design of the pendulum and assumes a relatively low level of friction but I'm more or less just referring to a string with a spherical weight suspended one one end and fixed to a fulcrum point at the other.
From my limited understanding of this matter I would think that the sum of the energy (mass X gravity X height) needed to send the bob flying past its point of equilibrium a number of times is collectively greater than the initial energy requirement to raise the bob from equilibrium to its point of maximum potential energy, this extra energy being drawn from Earth's gravity.
Can someone please confirm if my understanding is correct of if not explain why and what is actually happening?
Thanks,
Abz
