#ScienceWithGray: The Idea Of Momentum: A Subject Of Physics

- By Aan Gray ✒️
Let me start by saying that Snooker players can perform some amazing moves on the table, without necessarily knowing Newton’s laws of motion. However, the laws of physics can help us to understand what happens when two snooker balls collide or when one bounces off the side cushion of the table.

Here are some examples of situations involving collisions:
I. Two cars collide head-on.
II. A fast-moving car runs into the back of a slower car in front.
III. A footballer runs into an opponent.
IV. A hockey stick strikes a ball.
V. A comet or an asteroid collides with a planet as it orbits the Sun.
VI. The atoms of the air collide constantly with each other, and with the walls of their surroundings.
VII. Electrons that form an electric current collide with the
vibrating ions that make up a metal wire.
VIII. Two distant galaxies collide over millions of years.
From these many examples, we can see that collisions are
happening all around us, all the time. They happen on the microscopic scale of atoms and electrons, they happen in our everyday world, and they also happen on the cosmic scale of our Universe.

In definition, Momentum is the product of the mass of a body and its velocity. Mathematically, m x v = mv. The Standard International Unit of Momentum is Newton-second, Ns.
Science can be a lot groovy, you know! 😺
