The arrow shows the direction of time. The further to the right, the longer time from the start. Distance runs vertically (the y-axis). The higher up the graph we go, the further we are from the start.PowerPoint Presentation: If something is not moving, a horizontal line is drawn on a distance-time graph Time is increasing to the right, but its distance does not change. It is stationaryPowerPoint Presentation: If something is moving at a steady speed, it means we expect the same increase in distance in a given time: Time is increasing to the right, and distance is increasing steadily with time ,it moves steadilyPowerPoint Presentation: Both the lines below show that each object moved the same distance, but the yellow line got there before the other one : A steeper gradient indicates a larger distance moved in a given time. In other words, higher speed. Both lines are of constant gradient, so both speeds are constantPowerPoint Presentation: It then suddenly increased its speed, covering a much larger distance in the same time.PowerPoint Presentation: The line below is curving upwards. This shows an increase in speed, since the gradient is getting steeper: In other words, in a given time, the distance the object moves is larger. It is accelerating.PowerPoint Presentation: By definition, speed = distance / time so the steepness (or gradient) of the line will give us the speed! Yellow: speed = distance / time = 30 m / 10 s = 3 m/s Blue: speed = distance / time = 20 m / 20 s = 1 m/sPowerPoint Presentation: Moving at a steady speed, slowly Not moving for quite some time Moving again, but at higher speedLinear Motion: Linear MotionPowerPoint Presentation: When an external force is applied to a body the rate of increase of momentum produced is directly proportional to the applied force Linear motion is motion along a straight line It can be uniform, that is, with constant velocity (zero acceleration), or non-uniform, that is, with a variable velocity (non-zero acceleration).PowerPoint Presentation: Linear motion is sometimes called rectilinear motion . Linear motion is the most basic of all motions An example of linear motion is that of a ball thrown straight up and falling back straight down.PowerPoint Presentation: Thank You You do not have the permission to view this presentation.
