Collision is defined as two objects colliding for a very brief period of time. In other terms, a collision is a reciprocal contact between two masses that occurs for a relatively brief period of time and results in changes in the momentum and energy of the colliding masses. You may have noticed the effect of […]

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsIn a physical system, the centre of mass is a point where the system’s total mass is believed to be concentrated. When the external force is applied to the system, it moves so that its mass is concentrated at that point. To understand the centre of mass in a two-particle system, we consider a system

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsThe average speed of an object is defined as the entire distance it goes divided by the amount of time that has elapsed since it started. Because it is defined solely by a magnitude, the average speed is unquestionably a scalar quantity. Average Speed The average speed is calculated using the following formula: Average Speed
Isaac Newton is one of the most well-known names in physics, and the most significant one when studying ‘Motion’. Newton, who lived from 1642 to 1727, formulated the three laws of motion in the year 1686. Newton’s three laws of motion are: Newton’s First Law of Motion: Law of Inertia Newton’s Second Law of Motion:

Class 11, IIT JEE, Laws of Motion, Newton’s laws of motion, PhysicsThe average velocity is calculated by dividing the change in velocity by the change in time. An object’s average velocity tells us nothing about what happens to it between its starting and finishing points. The more detailed the input, the smaller the time intervals considered in a motion. We’re left with an infinitely small gap
Uniform motion is described in physics as motion in which the velocity of a body travelling in a straight line remains constant. A uniform motion occurs when the distance travelled by a moving object is the same at multiple time intervals, regardless of time length. As there is a constant velocity with regard to time,

Class 11, Dynamics of uniform circular motion, Laws of Motion, NEET, PhysicsIntroduction In 1609, Johannes Kepler gave his first two laws of planetary motion after examining Tycho Brahe’s astronomical data. After a gap of 10 years, he reported his third law in 1619. Before starting his research on planetary motion, he believed in the Copernican model of the solar system like many of his time. The

Class 11, Dynamics of uniform circular motion, Laws of Motion, NEET, PhysicsInstantaneous velocity refers to the rate at which a position changes in a very short time period (almost zero). Measuring in SI units m/s. The magnitude of the instantaneous velocity is instantaneous speed. It is the same as instantaneous velocity however without any direction. Simply put, it is the object’s velocity at that moment in time. Therefore the speed

Class 11, Dynamics of uniform circular motion, Laws of Motion, NEET, PhysicsFriction is said to be a necessary evil and is all around us. It is a force that acts on a surface that is in contact with another surface, and it impedes the motion of the objects. This means that friction is an opposing force that resists the object’s motion. It is responsible for bringing
