Definition: A vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.

Alright class, settle down and let’s take a look, At ‘velocity,’ a concept we need to cook! The dictionary gives us a helpful clue, But let's break it down for me and you. It says "a vector quantity," that’s the key, Meaning it has both direction – you see? Think of a car speeding on the road, Moving fast, a heavy load! The speed is how quickly it goes by, But velocity adds a directional sigh. It's “the rate of change of position with time,” How far something travels, in rhythm and rhyme! Imagine a runner, swift and free, Moving across the grassy lea. They’re not just moving, that's plain to see, But how they’re moving – directionally! So velocity includes both speed and sway, And where it’s going, day after day. It's like saying "5 miles per hour east," you see? That tells us the speed and where it will be! Does that make sense to everyone here? Any questions about this important concept? Don't be shy – let’s discuss!
