 So here is the eighth question. It says define uniform velocity, uniform velocity. So let me pick up a color from here and yes, uniform velocity and uniform acceleration. This is what we have to define. Okay, so let's talk about uniform velocity. So I'm writing definition of uniform velocity. So in such questions, always define and try to give an example to support your answer. Okay, so definition as well as example to support your answer. So what is uniform velocity? Uniform velocity is if an object or particle moves in a straight line. So this is very, very important for uniform velocity. It moves in a straight line in one direction, in one direction, in one direction. Such that, such that it covers, it covers equal, equal distance. Or in this case you can also say displacement but hardly matters because it's already a straight line in one direction. It covers equal displacement in equal intervals of time. Then, then the object, object is said to be, said to be undergoing, undergoing uniform motion or undergoing motion, motion with uniform velocity, uniform velocity. Okay, and now let's give an example. So for example, for example, though it is very difficult to find out an ideal example for uniform velocity, it hardly happens in our day to day life but ideal case could be, for example, a ball rolling on a, or don't give examples of rolling that will be little, or an object, let's say a block moving on a frictionless, frictionless is important because no force should be acting, frictionless, horizontal table, horizontal. Table, right? Because in one direction also, right? In one direction, in one direction. Had it been for a more mark here, it is only for two marks so it is easy and we don't need to do much but let's say information wise you can draw a diagram as well. You know, draw a diagram and show an object here and it is moving with a uniform velocity. Right? This is a table, table. Okay, this is uniform velocity. What about uniform acceleration guys? So uniform acceleration, acceleration, what about uniform acceleration? So uniform acceleration is nothing but if the change, change in velocity, now I'm not talking about velocity only, I'm talking about change in velocity. It's a change in velocity of an object moving in a straight line, moving in a straight line, right? Moving in a straight line, straight line. Though you have already taken the word velocity but it's always good to highlight that that the object is moving in a straight line in the same direction, in the same direction, one direction, that is any one direction, right, left, up, down. If the change in velocity of an object moving in a straight line in the same direction is constant or equal in equal intervals of time, equal intervals of time. That means let's say if you're talking about one, one second each, so in every once again same amount of velocity should be, the velocity difference in that one second will be same, should be same. Then the body is said to be, said to be undergoing, undergoing a motion with uniform acceleration, uniform acceleration. I hope you understood. Okay, and what will be example? So I'm just writing example in short. For example, freely falling body, freely falling body is undergoing uniform acceleration and that is acceleration due to gravity. Okay, just an added information here. You must know this because you must be ready for all exigencies. You must know that uniform velocity curve, something like that. So if I plot T and V, right, VT curve, then this is my uniform velocity. Okay, uniform velocity, velocity is not changing. And in this case, the VT curve will be a straight line, like that inclined line is where uniform acceleration. So please have this much information. So if it is a four marker or five marker, then you can add these information over there as well. I hope you understood this. So let's take the next problem.
