The vibration in which a body oscillates under the effect of an external periodic force, whose frequency is different from the natural frequency of oscillating body are called forced oscillations. In forced vibrations, the oscillating body vibrates with frequency of external force and amplitude oscillations is generally small. Examples of Forced Oscillations in Everyday Life …
A block and tackle is a type of compound pulley. It has a number of fixed pulleys sharing one fixed axle at the top. This group of fixed pulleys is called the block. The block is connected by ropes to a set of movable pulleys at the bottom end of the ripe. This part is …
A pulley is a machine in which a rope or cable passes back and forth over one or more grooved wheels. In a pulley system, one end of the rope is attached to the load and the other end is pulled in order to move or lift the load. A single pulley has only one …
When an object moves while rotating along a circular path, it is said to be in circular motion. Circular motion is further divided into two categories: uniform and non-uniform circular motion. In our previous post, we explored uniform circular motion. Now, let’s turn our attention to non-uniform circular motion. This occurs when an object moves along …
A frame of reference is essentially a set of coordinate axes used to define an object’s position in two- or three-dimensional space. It can also be defined as a set of coordinates used to record the position and time of events. There are two types of frames of reference: inertial frame of reference and non-inertial frame of …

To describe the motion of an object, we need a frame of reference. A frame of reference is essentially a set of coordinate axes used to define an object’s position in two- or three-dimensional space. It can also be defined as a set of coordinates used to record the position and time of events. The …
Stable equilibrium is a condition where an object, once slightly displaced from its original position, tends to return to that position on its own. In other words, if you give the object a gentle push or move it a little, it will naturally come back to where it started. Think of it as a “return …
Lenz’s Law is a fundamental law of electromagnetism that describes the direction of an induced electric current in a conductor when the magnetic field around it changes. It states that the direction of the induced current is such that it opposes the change in the magnetic field that produced it. Lenz’s Law has important applications …
Ever wondered what concept scientists use in the design of engines, turbines, and other rotating machinery, as well as in the study of celestial mechanics, such as the motion of planets and stars? Anyone interested in the mechanics of rotating objects must understand angular velocity. By learning about the properties and characteristics of angular momentum, …
