. If heavier objects were accelerated by gravity at a greater rate, what result would you have expected in measuring the period of the two pendulums of the same length but with different masses for the bob?
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.
Physical science Simplify please
1. Explain how the results from Parts 1 and 2 verify Newton’s Second Law. If heavier objects were accelerated by gravity at a greater rate, what result would you have expected in measuring the period of the two pendulums of the same length but with different masses for the bob?
2. How close were your results to the known value of g, 9.81 m/s2 based on your percent error? What kinds of errors could have resulted in the difference in your result versus the actual known value of g?
