Definition

Momentum is the quantity of motion of a moving body, defined as its mass multiplied by its velocity. It describes how difficult it is to stop a moving object. Think of a bowling ball rolling down the lane 🎳 or a car accelerating on the highway 🚗. The heavier the object and the faster it's moving, the more momentum it has. Momentum is a key concept in physics. It applies to both linear and rotational motion.

Etymology

"Momentum" comes from the Latin word "momentum," meaning "movement," "impulse," or "weight." It originally referred to the force or influence that sets something in motion. Over time, it evolved to describe the quantity of motion itself. It highlights the connection between force, movement, and weight. It retains a clear link to its root meaning of movement and impulse.
