An object is placed on a vertical spring. You compress the spring and the release, sending the object into the air. With this information i. The value of gravitational acceleration 10mls² ii. The mass of the object 15kg iii. The spring constant 250Nm iv. The compression of the spring 0.1m (b) Draw photos of the system at the following times: i. The instant the spring is released. ii. The instant the object reaches its original position before you compressed the spring. iii. The instant the spring is uncompressed. iv. The instant the object reaches its peak of motion. (c) Calculate the height and velocity of the object in each picture
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.
