A pendulum is swinging back and forth in periodic motion. At the highest point (the moment that the pendulum stops moving up), the mass at the end has a gravitational potential energy of 3.0J. As it swings down, there is a point at which the gravitational potential energy is reduced to 1.0 J. What is true about the energy of the pendulum during this time? Your answer: The gravitational energy and kinetic energy are both going to be 1.0 J at the same time. The kinetic energy will be 2.0J when the gravitational potential energy is 1.0 J. The kinetic energy will remain constant during this motion. The total energy of the pendulum will increase and decrease as it moves.
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.
