### 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.

### 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

### Kepler’s law of period

Kepler’s law of period Kepler’s law of period for planetary motion According to Kepler’s laws of period for planetary motion, the square of the period of revolution of as planet around the sun is directly proportional to the cube of the semi-major axis of its orbit. Mathematically, it can be

### Moment of Inertia of a Rod having non-uniform, linearly increasing mass density

Moment of Inertia of Rod having non-uniform, linearly increasing mass density Moment of Inertia Moment of inertia is of great importance when we come to discuss the rotational dynamics. The the word “inertia” refers to resistance against any change in state of object (mass). Specifically, the moment of inertia is
