Moment of inertia is the force required to change the speed of a rotating object. It was introduced by Leonhard Euler in 1730 and is calculated using the formula I = km r2. Objects with an awkward shape require experiments to determine velocity. Practical applications include determining how quickly a car will spin out of […]
Inertia is an object’s resistance to a change in motion, related to Isaac Newton’s first law of motion. Inertia depends on mass and is used to measure mass independently of gravity. Examples of inertia include a car’s resistance to a change in motion and rotational inertia. The origin of inertia is still unknown. In physics, […]
