Definition: Of a body in motion: the tendency of a body to maintain its inertial motion; the product of its mass and velocity.

Alright class, settle down, let’s take a look today, At a tricky word that needs a thoughtful way. It's “momentum,” a concept quite grand, Let’s break it down with understanding at hand! The dictionary gives us a clue, you see, "Of a body in motion...it’s meant for you to agree!" It talks about inertia , that stubborn desire, To keep moving forward, setting things afire – (figuratively speaking, of course!) Think of a bowling ball, rolling down the lane, It keeps on going, defying any strain. That’s momentum at work, you understand? Maintaining its motion across the land! Now let's look at the part that’s crucial and bright, "Product of its mass and velocity” – shining light! Mass is how much stuff a body contains, Like a feather or boulder, it eases or strains. And velocity , that speed with direction too, How fast and where something's moving for you! So momentum’s the answer, a combined decree, Mass times velocity – that's what it will be! In short: Momentum is how hard it is to stop, The more mass you have, the harder to drop! And faster you move, with greater speed and might, Momentum’s stronger, shining ever bright! Any questions? Don't hesitate to ask, Let’s make sure this concept truly will last!
