Inertia
What is inertia? When we talk about inertia, we’re really talking about one of the most foundational ideas in all of physics. What inertia captures is the tendency of physical systems to resist changes in…

Impulse
Impulse in physics is a concept that connects force and motion over time. It describes how much a force changes an object’s momentum, emphasizing that not only the strength of a force matters, but also…

Inductance
Inductance is a fundamental property of electric circuits that describes how a changing electric current creates and responds to magnetic fields. When current flows through a wire, it produces a magnetic field around that wire.…

Interference
Interference is one of the most striking demonstrations of the wave nature of physical phenomena. It occurs when two or more waves meet in space and time, causing the total displacement at any point to…

Inertial Frame of Reference
In physics, the concept of an inertial frame of reference is one of the most fundamental and indispensable ideas that underpins our understanding of motion, forces, and the laws of nature. When we observe the…
