A block of known mass is suspended from a fixed support through a light spring. Can you find the time period of vertical oscillation only by measuring the extension of the spring when the block is in equilibrium?
Yes, the time period of the vertical oscillations in the spring can be determined. The time period of a simple pendulum is shown below. When pendulum is replaced by spring, them mg=kx. Hence, by determining the extension in the spring, the time period can be obtained.
It is proposed to move a particle in simple harmonic motion on a rough horizontal surface by applying an external force along the line of motion. Sketch the graph of the applied force against the position of the particle. Note that the applied force has two values for a given position depending on whether the particle is moving in positive or negative direction.
A hollow sphere filled with water is used as the bob of a pendulum Assume that the equation for simple pendulum is valid with the distance between the point of suspension and centre of mass of the bob acting as the effective length of the pendulum. If water slowly leaks out of the bob, how will the time period vary?
