The Boffins' Portal Team Significant figures (often called sig figs) are the digits in a number that carry real meaning about its precision. They include all the certain digits in a measurement plus the first uncertain (or estimated) digit. In simpler words, significant figures show how accurate and trustworthy a number is. There are a few important rules to …
When an object is left to vibrate freely, it doesn’t keep swinging or shaking forever. Little by little, its energy gets drained away by things like air resistance, friction, or even internal effects like hysteresis or electromagnetic forces. Because of this energy loss, the vibrations get smaller and smaller over time. This gradual fading of …
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 …

Instantaneous velocity of an object is the velocity of the object at any instant of time or at any point of its path. Instead of looking at how fast something travels on average, it focuses on the exact rate of motion at any given moment. Think of it like glancing at a car’s speedometer—you see …
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 …
In physics, there are many types of motion, including linear motion, rotary motion, oscillatory motion, and periodic motion, to name a few. When an object moves while rotating along a circular path, it is known as circular motion. Circular motion is further divided into two categories: uniform and non-uniform circular motion. Today, we’ll focus on …
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 …
