What’s Schrödinger’s Cat, and Why Is It Both Dead & Alive? 🐱📦 Schrödinger’s Cat is a famous thought experiment in quantum mechanics. Imagine a cat inside a box with a radioactive atom, a Geiger counter, and a vial of poison. If the atom decays, the Geiger counter detects it, breaking the vial and killing the …

Electromagnetic (EM) waves are waves of electric and magnetic fields that travel through space at the speed of light. These waves do not require a medium to propagate, meaning they can travel through a vacuum (such as space). Key Properties of Electromagnetic Waves: Electromagnetic Spectrum: EM waves exist in different forms, classified by their wavelength …
This is a simulation of a bar magnet and its magnetic field. Here’s what is happening: This simulation allows users to explore how a bar magnet interacts with its surroundings and how the strength and polarity of a magnet affect its magnetic field.
The key differences between distance and displacement are based on their nature, measurement, and relation to the motion of an object: 1. Definition: 2. Nature: 3. Value: 4. Path Dependence: 5. Magnitude: 6. Example: Summary Table: Feature Distance Displacement Definition Total path length Shortest straight-line distance Nature Scalar Vector Value Always positive Can be positive, …
Acceleration is the rate at which an object’s velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration occurs when an object speeds up, slows down, or changes direction. Formula for Acceleration: Where: Key Points to remember about Acceleration: Example: Slowing Down (Deceleration): If a bike is moving …
Velocity is the rate at which an object changes its position in a specific direction. It is a vector quantity, meaning it has both magnitude (speed) and direction. Velocity tells not just how fast something is moving (speed), but also in which direction it is moving. Formula for Velocity: Key Points: Example: Thus, velocity gives …
Distance refers to the total length of the path traveled by an object, regardless of its direction. It is a scalar quantity, meaning it only has magnitude (size) and no direction. Distance is always positive and cannot decrease as an object moves, because it represents the cumulative length of the path covered. Key Points: Example:
For JEE Main + Advanced Physics and Board Exams In kinematics, motion refers to the change in position of an object over time. It describes how objects move, but not why they move (which is the focus of dynamics). Kinematics studies motion in terms of displacement, velocity, and acceleration, without considering the forces causing the …
