Rotational Motion

Rotational motion is one of the most observed phenomena in the physical world. The rotating of the wheels, the fan spinning overhead, even the planet we live on is rotating about its axis. Therefore, rotational motion plays a very important part in kinematics. According to thermodynamics, the entropy of the universe is constantly increasing. In […]

Introduction A rigid body is a simplified version of a solid body that does not deform. In other words, regardless of external forces acting on a rigid body, the distance between any two points remains constant over time. An example of a rigid body is a metal rod. When a rigid body is in pure

The spinning motion of an object around its own axis is known as “rotation.” The orbital motion of one thing around another object is known as “revolution.” The Earth, for example, revolves on its own axis, resulting in a 24hour in a day. The 365 days are created by the Earth’s rotation around the Sun.

We encounter different types of friction in our daily lives – from burning a matchstick to writing on a paper. Friction produces heat and sound when there is relative motion between two objects. Friction is the resistive force that occurs due to molecular adhesions and roughness of the surfaces. This force opposes every motion of

Introduction Friction is the resistive force that an object faces whenever it is facing a change in its state of motion. There are four types of friction: static, kinetic, rolling, and fluid which is also known as drag.  When an object rolls on the floor, instead of being dragged or sliding, the rolling friction comes

In physics, projectile motion refers to motion that is shot or flung in a straight line, without a change in direction or speed. This type of motion is often associated with projectiles and projectiles are a basic example of projectile motion. Projectile motion can be used to describe the motion of a cannonball, a bullet,

Any object which is thrown into space and the only force acting upon it is gravity then that object is called Projectile and the motion which the body undergoes is called Projectile motion. The path undertaken by the projectile is known as Trajectory.   We tend to assume that the object is near to the surface

The time it takes any string element to perform one complete vibration is defined as the period of oscillation T of a wave. A scalar measure of rotation rate is angular frequency (also known as angular speed, radial frequency or the circular frequency. It shows the rate of variation of the phase of a sinusoidal

The orbital speed is the speed with which an object revolves around a larger object or orbits around the barycenter. If it is calculated during the revolution of a smaller body around a larger body, its speed is relative to the centre of mass of the larger body. This term denotes both the average speed

An object that moves or rotates in a circular path is said to have circular motion. Circular motion is classified into uniform and non-uniform circular motion based on its rate of rotation. A body with different motions at different points along its path of motion is called a non-uniform circular motion. Centripetal force plays a
