Distance is a scalar quantity. SI unit of distance is metre.Displacement is the shortest distance covered by a moving object from the point of reference (initial position of the body), in a specified directio..

Two Bodies of Mass m Separated by a Distance 2d ..

Distance and Displacement - The distance between terminus A and terminus B is 150 km. A bus travels from terminus A to terminus B. The distance covered by the bus is 150 km. The bus travelling on the same route, returns from terminus B to the terminus A. Thus the total..

A distance-time graph is a line graph showing the variation of distance with tim..

In a distance-time graph, time is taken along x-axis and distance along y-axis. Note: Line graph is a graph which shows the dependence of one quantity on another quantity..

Force of Attraction Between Two Bodies of Mass m Separated by a Distance 3d That is, when the distance is doubled, the force will be reduced to 1/4 t h of the original value of force and when the distance is increased three times, the force will be reduced to..

. Draw perpendiculars from A and B to x and y axes. Join A to C to get a right angled triangle AC..

Now, let us see the nature of distance-time graph for a non-uniform motion. The following table gives the distance covered by a bus after every 15 minutes. Distance covered in Km 0 5 15 20 25 30 35 Time in Minutes 0 15 30 45 60 75 90 From th..

Graphs can be easily read at a glance.Plotting graphs takes less time and is more convenien..

The figure below gives the speed-time graph of a car moving with a uniform speed of 60 km/h for 5 hours. Speed-Time Graph of a Car Moving with Uniform Speed Distance travelled by the car (S) = v x t But 60 km/h = OC = breadth of the rectangle OABC 5h = OA = length of the rec..
