have a pendulum clock that shows an accurate time on the Earth, and it is found that the same clock runs slow by a factor of 2.45 on the new planet. Describe how you can use this information to find the unknown gravitational acceleration. Make the necessary calculations and post your result. Make a new thread and complete the following about the real-world applications of this concept: You just installed a new swing in your backyard. When you are swinging, you are 168 cm from the point where you attached the swing. Calculate how long it will take for the swing to complete 4 complete cycles and post your result.
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
