The Laws of Momentum: Why Moving Objects Keep Going

What Is Momentum? – Momentum is the “oomph” of motion, combining an object’s mass and velocity.
Formula for Motion – Momentum is calculated as mass × velocity (p = m × v).
Bigger Mass, Bigger Push – Heavy trucks carry more momentum than small cars at the same speed.
Speed Boosts Momentum – Even a light object, like a baseball, packs punch when moving very fast.
Newton’s First Law – Objects keep moving in a straight line unless an outside force changes their momentum.
Collisions Show It – In crashes, momentum transfers between objects, explaining why billiard balls scatter.
Conservation Rule – The total momentum of a closed system stays constant, even if objects bounce or stick together.
Everyday Example – Catching a fast ball stings because your hand must absorb its momentum.
Space Connection – Astronauts floating in space keep drifting until another force redirects them.
The Universal Principle – From sports fields to galaxies, momentum explains why moving things keep going.
