that's the problem in my classes we never work with pendulums only with springsharuspex said:If you cannot yet attempt the energy equation, start by identifying the mass centre the question refers to and adding the angle it mentions to the diagram.
Then list the forms of energy that need to be in the equation, then the variables which contribute to those.
I do not see how that prevents you from attempting the steps I listed. Have a go.misterpicachu said:that's the problem in my classes we never work with pendulums only with springs
the mass centre gave me (√3/2)*L and then I used it as the height in the potential energy formula, is that ok?haruspex said:I do not see how that prevents you from attempting the steps I listed. Have a go.
Height from what baseline? And what about the angle θ?misterpicachu said:the mass centre gave me (√3/2)*L and then I used it as the height in the potential energy formula, is that ok?
Simple harmonic motion is a type of periodic motion in which an object oscillates back and forth around an equilibrium point, with a restoring force that is directly proportional to the displacement from the equilibrium point.
The key characteristics of simple harmonic motion include a constant period (time for one complete cycle), a sinusoidal displacement graph, and a constant amplitude (maximum displacement from equilibrium).
The period of simple harmonic motion can be calculated using the equation T = 2π√(m/k), where T is the period, m is the mass of the object, and k is the spring constant.
The frequency of simple harmonic motion is the inverse of the period, meaning that as the period increases, the frequency decreases and vice versa.
The amplitude of simple harmonic motion determines the maximum displacement of the object from its equilibrium point. A larger amplitude results in a greater maximum displacement and a longer period, while a smaller amplitude results in a smaller maximum displacement and a shorter period.
