A pendulum makes 10 swings every 15 seconds on Earth. You take the same pendulum to the surface of a different planet and you notice that the pendulum makes 15 swings in 15 seconds. Which of the following could be true? (Select two right answers) Group of answer choices The mass of the planet is larger than Earth The mass of the planet is smaller than Earth The radius of the planet is larger than Earth The radius of the planet is smaller than Earth
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.
