This article covers the Punjab Board's 2025–2026 Class 11 Physics Syllabus. Class 11 students can download the syllabus in PDF format to become acquainted with the subjects that will be studied during ...

In these gaps, we have discovered that systems don’t quite align, and people end up navigating workarounds instead of actual ...

The integration of cyber capabilities with traditional warfare creates new vulnerabilities and escalation risks.

People in the power industry understand inertia and its importance to grid stability. As large thermal power plants and other ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

For heavy duty trucks like semis hauling lots of cargo over long distances, conventional friction brakes just can't do it on their own. To maintain safe speeds and prevent overheating on long ...

Kinetic energy can be transformed into other forms of energy, such as potential, thermal, or electrical energy, and vice versa. For example, when a car stops, its kinetic energy is converted into ...

For about 15 minutes on July 21, 1961, American astronaut Gus Grissom felt at the top of the world – and indeed he was.

The kinetic friction between the water and the tubing surface opposes the water's forward motion, resulting in a loss of pressure. In irrigation lingo, we call this "pressure loss from friction" or ...

What is regenerative braking? Commonly referred to as ‘regen’ braking, it's a process an electric car uses to regain kinetic energy that would otherwise be lost during braking.

Cars stop by changing kinetic energy into heat. Modern cars use a system of brake disc rotors, calipers, and brake pads to create friction and stop a car.
