 So here is the fifth question. It says differentiate between distance and displacement. This is the most typical question in motion, especially in grade nine and you know already. So the best way to answer this question you all know is to create a table and then differentiate. So let's say in your notebook, you can create a table like this and here you can write distance. So we are going to write the point related to distance here and here a displacement. Displacement, okay? So let's begin. So what is the first quantity? First point should be related to definition. So you write distance is it is the path length or it's better to add a word. It is the actual path length between, between starting and starting and end point, points. Okay, this is the first point. What about displacement? Displacement is nothing but the shortest, shortest distance, distance between, between the starting, starting and end point, isn't it? So basically we are talking about the definitions first. So in the first point, we just gave the definition of distance and displacement. Second is it's a scalar quantity, all of us know. It's a scalar quantity, correct? There is no mention of any direction, right? Here you'll say it is a vector quantity. So this is another point of difference. It is a major, major point of difference. It is a vector quantity, correct? Correct, what else? What else is there? So if you see distance is, distance is, distance is zero, either zero. That means it can have zero value. That means there's no distance or no difference between starting and end point. Distance is either zero or positive. It will always be either zero or positive. If it is not zero, then it has to have a positive value. But in case of velocity displacement, it can have, it can have negative values as well. Apart from being zero and positive values, it can have negative values as well, right? When is that case? Let's say if this is the origin and this is your coordinate system or frame of reference and this is origin and let's say this is positive. So hence, if a particle moves in this direction, then we say that the displacement is negative, isn't it? Now you can also give examples by drawing that's also a good practice or distance. You can draw a path like this. This is starting point A and B, okay? And if you do this, you write this as displacement. This as displacement, no doubt. And this is distance, okay? This is what the drawing can also be helpful here. Okay, fourth point of difference will be distance is, distance is always greater than, greater than or equal to or equal to displacement, displacement. So in any case, let's say here in this case, there's a distance is this the path length and AB is the displacement. So hence, any path length joining AB will be either equal to the displacement AB, the minimum possible is this or it will be greater than displacement, correct? On the other hand, displacement is displacement. Displacement, displacement's magnitude you can see because it is a vector quantity. So hence you can't say displacement is here also. You can say equal to the magnitude of displacement. So displacement's magnitude is always lesser than or equal to distance between two points. The two points have to be the same. Distance between two points, okay? Start and end point, please keep in mind. Another point of difference could be that there could be so many distances between A and B. You can have different, different paths. So let's say if you have a path like that, then also. So there could be infinitely many distances between two points but there could be only one displacement between A and B. Correct? So if I take another color just for your understanding, let's say I take this and yes, if I draw the, if I join A to B, so there is only one displacement possible if two points are fixed. You can reach the destination from the starting point through multiple distances. For example, let's say you want to go to your school from your home so you can go to your friend's place and then from friend's place you can go to your school. That's one way of doing it. So let's say this is your home and this is your school. So you can go to your friend's place, F1, let's say and then go to school. That could be one way. You can go to another friend's place, F2, let's say and then from here you go to school or you directly go from your place to school in a straight line path. So hence this will be displacement and all other routes becomes the example of distance. I hope now you are clear between the difference between distance and displacement.
