A 225 g mass is suspended from a vertical spring. It is then pulled down 15 cm and released. It completes 10 oscillations in 32 seconds. What is the force constant (k) of the spring in N/m
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.
- A 225 g mass is suspended from a vertical spring. It is then pulled down 15 cm and released. It completes 10 oscillations in 32 seconds. What is the force constant (k) of the spring in N/m
- A block of unknown mass is attached a spring with a spring constant of k = 6.50 N/m. The mass undergoes
simple harmonic motion with an amplitude of 10 cm. When the block is halfway between the equilibrium position and the end point, its speed is 0.30m/s a.) Calculate the mass of the block. b.) Calculate the period of oscillation.
