3) How does the total mechanical energy in the oscillating system change as it oscillates?

4) Calculate the frequency of oscillation for a 3 meter long simple pendulum swinging on the Moon, where g= 1.62 m/s². Calculate the frequency of oscillation for a 3 meter long simple pendulum swinging on the surface of a white dwarf star the size of the Earth but equal to 1 solar mass, where g= 3.27E6 m/s².

Expert Solution

1. Simple harmonic motion (SHM) is a special type of oscillation in which the particle oscillates on a straight line, the acceleration of the particle is always directed towards a fixed point on the line and its magnitude is proportional to the displacement of the particle from this point. This fixed point is called the centre of oscillation.

Lab 11. Simple Harmonic Motion Introduction Lots of things vibrate or oscillate. A vibrating tuning fork, a moving child’s playground swing, and the speaker in a headphone are all examples of physical vibrations. There are also electrical and acoustical vibrations, such as radio signals and the sound you get when blowing across the top of an open bottle. Adding heat to a solid increases the vibration of atoms and molecules. One simple system that vibrates is a mass hanging from...
