A block of mass m = 3.98 kg is attached to a spring, which F (N) is resting on a horizontal frictionless table. The block is 5- pushed into the spring, compressing it by 5.00 cm, and is 4 then released from rest. The spring begins to push the block 3 - back toward the equilibrium position at x = 0 cm. The 2- graph shows the component of the force (in Newtons) 1- exerted by the spring on the block versus the position of the x (cm) block (in centimeters) relative to equilibrium. Use the graph -5 -3 -2 3. 4 5 -1 to answer the questions. -2 -3 How much work is done by the spring in pushing the block -4 from its initial position at x = -5.00 cm to x = 2.64 cm? -5- -6 work: J I TOOLS x10 What is it reaches x = 2.64 cm? speed: m/s
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.
