Video narration
If you walk around a block at the same pace, are you keeping the same velocity the whole time? It feels like yes. Your speed is steady: you're moving at the same rate. But speed tells you how fast you move. Velocity adds direction-the way you move. Picture the walk. You move along one side of the block, then turn a corner and continue along another. You never speed up or slow down. But at the corner, your direction changes. So your velocity changes too. That's the key: speed can stay constant while velocity changes, because velocity includes both how fast you move and which way. The pace has not changed; the path has. So, do you keep the same velocity just because you keep the same pace? No. Your velocity changes whenever you turn, even if your speed stays exactly the same.
