Motion

In order to understand the concept of wave motion, let us drop a stone in a trough of water. We find that small circular waves…

Wave motion is a mode of transmission of energy through a medium in the form of a disturbance. It is due to the repeated periodic…

In the case of forced vibration, if the frequency difference is small, the amplitude will be large (Figure). Ultimately when the two frequencies are same,…

When a vibrating body is maintained in the state of vibration by a periodic force of frequency (n) other than its natural frequency of the…

Oscillation is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time. The most common examples for…

From the expression for the time period of oscillations of a pendulum the following laws are enunciated: (i) The law of length: The period of…

A simple pendulum consists of the massless and inelastic thread whose one end is fixed to a rigid support and a small bob of mass…

Consider a non-viscous liquid column of length/of uniform cross-sectional area A (Figure). Initially, the level of liquid in the limbs is the same. If the…

When two Springs are Connected in Parallel: Two springs of spring factors k1 and k2 are suspended from a rigid support as shown in Figure.…

Consider a mass (m) attached to an end of a spiral spring (which obeys Hooke’s law) whose other end is fixed to a support as…
