- Now, velocity is not that hard to understand as well. It's pretty similar to speed. It also determines how fast something is moving, but the twist is that it includes direction. So it's not just how fast, it also involves where something is headed to. Compared to speed, velocity is a vector quantity,
- VELOCITY
- I told you, the difference between speed and vector, and scalar and velocity is really easy.
- You're right, dad! I understood the terms very well. But I'm still having trouble on displacement and distance.
- DISPLACEMENT
- You're right. We still have the difference between Displacement and Distance. Well, let's find out how they're similar first. These two are used to measure two points: the starting point and the ending point.
- vs
- DISTANCE
- Interesting...
- Let's talk about distance first. For example, we are going to the beach right now. Our starting point is our house and then we went by the town road, the expressway, and the road we are in right now. This is distance, the overall length of the path we took just to get to the beach.
- DISTANCE
- I see, so distance is basically all of the paths we took from our starting point until we get to the beach. I get it now.
- Now displacement is much easier to understand. It is a vector quantity, again when we say vector, direction is involved. Displacement simply means the direction pointing from the starting point to the ending point. Home is our start and the beach is our final destination, which is south of our house.
- DISPLACEMENT
- The difference is so clear now. Thank you, dad! And look, I can see the sand. We are finally reaching our ending point!
- We'll get to the more specific terms now. Speed talks about how fast something is moving. We can say that a car is in motion because it is moving, but if we add a detail of how fast it is moving, we get its speed.
- I heard that speed is also a scalar quantity because it only talks about magnitude units
