The topics that are covered in this video are listed here: We first take up a topic to learn about Describing Motion. Here we study about Motion along a straight line, Uniform motion and non-uniform motion. We then focus our attention to Measuring the Rate of Motion wherein we study Speed with Direction. Then our next topic of discussion will be Rate of change of velocity which is also known as Acceleration. We then move on to a very important topic of the Graphical representation of motion. Here we learn two types of graphs – the Distance - time graphs and the Velocity - time graphs. After learning about these graphs we derive the Equations of motion by the graphical method. There the three equations learnt will be Equation for velocity-time relation, Equation for position-time relation and Equation for position-velocity relation. We then end the video with the knowledge of Uniform circular motion.

Apart from these topics you could also learn about some related topics of Average Speed and Velocity, Units of distance, displacement, speed and velocity, Odometer, Retardation, Deceleration, Uniform and Non-uniform Acceleration, Average velocity in Uniformly accelerated Motion, Calculations using graph – Speed using the slope of distance - time graph, acceleration using the slope of velocity – time graph, distance or displacement using the velocity - time graph; Discontinuing Circular Motion, Frame of reference, Absolute motion, Location of an object in space, Jerk, Analogy between linear motion and rotational motion.
