• Suppose a car starts moving in a curved path from this point A and travels to point B and then stops at point C. br • Point A is its initial point and point C is its final point. br • The distance from A to B is 60m and from B to C is 30m. So the total distance is 90 meter. And the time it takes to cover this distance is 30 sec. br • Now let’s first find its speed. br • Dividing the total distance by total time here comes speed that is 3ms br • But for velocity we’ll not calculate whole distance but the displacement from first point A to final point C. and that is 45m. br • Now divide total displacement by total time and we get the velocity by dividing total displacement 45m to total time 30sec. we get the answer of 1.5 br • So velocity is 1.5msec. toward north. br • So to find speed we’ve to calculate total distance and to find velocity we’ve to calculate total displacement from first point to last point. Simple.
