Kinematic equations

The information on this page is ✔ fact-checked. The kinematic equations refer to a set of four equations that involve five key variables: displacement (Δx), acceleration (a), initial velocity (vi), final velocity (vf), and time (t). These equations serve as a powerful tool for analyzing the motion of objects. Each equation contains four known kinematic … Read more

Pressure equation

Update: This page’s content is moving to a new address in the upcoming months. The information on this page is ✔ fact-checked. The pressure equation states that pressure (P) is calculated as the ratio of force (F) to the surface area (A). Mathematically, the formula for pressure is expressed as P = F/A. This equation … Read more

Moment of inertia

The information on this page is ✔ fact-checked. Moment of inertia, also known as rotational inertia, is a measure of an object’s resistance to rotational motion. It depends on the object’s mass distribution. The moment of inertia of a point mass rotating around an axis at a distance r is given by the formula I … Read more
