 physics channel for physics please subscribe my channel hello and welcome back to another episode of physics partner motion graphs are a fundamental concept in physics and can be a challenging topic for many students to understand with the complexity of the subject and the intricate mathematical calculations involved it's no wonder that many students struggle to grasp the concept however fear not in this video we will be introducing you to virtual labs a revolutionary motion graph tool that makes learning and understanding motion graph easier than ever so without wasting time let's perform some virtual lab and try to understand different types of graphs associated with motion so let's understand the different types of graph with the help of this virtual lab on my left side you can see the speedometer which will show the value of the speed of the car the first graph we are studying is the motion with constant velocity and we will study three different graphs number one is the graph of cover distance with respect to time second will be the graph of velocity with respect to time and third with the graph of acceleration with respect to time and finally we will compare all three so let's start with the constant velocity and see how graph is going to be generated so you can see I started with the fixed velocity and you can see here the distance is going to be increased so whenever you create a graph of a motion with constant velocity the distance time graph will be a straight line which will show some inclined or gradient so if you calculate the gradient you can also get the value of velocity so you can see right now how much distance has been covered is 0.058 kilometers let's compare with other let's see the velocity time graph with the same value you can see here velocity graph will be parallel to the time because there is no change in velocity for example start with 5 so it is always be 5 it is constant throughout the journey so there is no change in it what about acceleration we know that with constant velocity there is no acceleration so there will be no graph because there is no acceleration produced because the car is moving with the constant velocity if you compare all three we can see the distance time graph for motion with constant velocity will be a gradient whereas the velocity time graph will be the straight horizontal parallel line to the time and there is no acceleration so there is no value of acceleration you can see acceleration is continuously 0 with the time spending because time never stops so there will be indication of time but there is no acceleration let's compare with different other velocities if I increase the velocity you can see my gradient will be more towards the y axis this will show the velocity has been increased you can see the velocity graph so this one is comparatively slower the blue one you can see the fastest and the orange one will be considered as the slowest in the graph so this is about motion with constant velocity now let's move to the graph motion with constant acceleration so let's see how the graph is going to be created when acceleration is constant so I'm going to start with a constant acceleration you can see the values here so you can see the curve here which shows the acceleration constant acceleration in terms of distance time graph if I check with velocity time graph remember this is constant acceleration line and the graph is between velocity and time so the gradient will consider as acceleration in terms of acceleration you can see the graph is simple horizontal parallel line to the time because acceleration is not changed you can see the acceleration is 10.0 meter per second square so it is a constant value and it's not going to be changed if we compare all three graphs you can see in distance time graph in terms of constant acceleration is a curve graph which is tilted towards the y axis whereas in velocity time graph for constant acceleration is a gradient straight line and there is a horizontal parallel line to time for constant acceleration there is no possibility of velocity zero because there is an acceleration which is constant it means the car is moving let's try and compare with others so you can see another one and if you notice the acceleration is decreased to one it is now one meter per second square so there is new line now acceleration decrease so you notice in case of acceleration decrease the gradient is now tilt towards the x axis let's try more acceleration to understand much better both lines purple and orange will show the constant acceleration so you can see different kind of acceleration lines according to the values if the values are high it's towards y axis if values are low it's towards x axis this is a graph about motion with constant acceleration let's move to our another graph which is motion with constant negative acceleration negative acceleration means the value is going to be decreased of the velocity like from high velocity to the lower velocity in terms of distance and time if you talk about constant negative acceleration you can see the curve here it means it's going to be declined the velocity is going to be decreased and the average distance cover is now less let's follow the pattern so this is the first graph and you can see here next let's compare these three constant negative acceleration graph in terms of velocity so in terms of velocity it will come from higher value to the lower value because as I told you it's a constant so there is a proper gradient this is a negative gradient now and it's coming from high velocity to the lower velocity with a particular span of time velocity is going to be decreased in terms of acceleration definitely it is parallel to the timeline because there is no change in acceleration it's constant it's negative but it's constant means the velocity is going to be decreased but the acceleration is remain constant if you compare all three graphs you can see so this is a distance time graph which is started with a gradient properly straight line and turns towards a curve whereas the velocity time graph is simply declined there's a negative gradient and acceleration is remain constant so I think it's enough for today so thank you very much for listening and watching I hope you enjoyed the video I hope this video is useful for you so take care of yourself and don't hesitate to write an email if you have any question curies suggestion and even classes are required take care of yourself meanwhile see you in the next video
