Kinematics: Understanding Uniform Motion
Kinematics: Understanding Uniform Motion What is Kinematics Kinematics is the branch of physics that deals with the motion of objects without considering the causes of motion. Among the various types of motion, uniform motion is a fundamental concept that provides a foundation for understanding more complex movements. In this article,

Force between the plates of charged capacitor
Force between the plates of capacitor Introduction Capacitors are fundamental components in electronics, used to store electrical energy. When a voltage is applied across the plates, an electric field develops, causing a charge to accumulate on the plates. The capacitor stores energy in the electric field created between the plates.

![Additional velocity](https://pcmtutorials.in/wp-content/uploads/2024/04/satellite.jpg)
A spaceship is launched into a circular orbit close to the earth’s surface. What additional velocity has now to be imparted to the spaceship in the orbit to overcome the gravitational pull.
Additional Velocity Required to Overcome Earth’s Gravitational Pull for Satellite Escape Escape velocity is the minimum velocity an object must attain to break free from the gravitational attraction of a massive body without further propulsion. For an object on the surface of the Earth, this velocity is approximately 11.2 kilometers
