Reading the graph: find distances travelled

[QUOTE="late347, post: 5460504, member: 531743"] Is it different in physics when you say: [U]distance travelled[/U], or [U]place?[/U] I think I got mixed up with that type of thinking myself, in the beginning. I should have read the instruction more carefully. Originally in the book it says that: The y-axis does denote place ( x metres). The x-axis does denote time (t seconds).[U][/U] Now that I think about it... I suppose in normal life, distance is defined by essentially the subtraction of two points. So if you have point at 5m and point at 45m, the distance is what is left in between the points really... which would be 40m. Mathematically you could even put the absolute value signs into that one. if the two points are the same point. Then the distance between them should be zero. I suppose that's true in the absolute value definition on the number line. Originally in the book it says that: The y-axis does denote place ( x metres). The x-axis does denote time (t seconds). The questions translated are: 1)which object has moved the most during 10 seconds. 2)which object has moved the least during 10 seconds. answer 1) I suppose that when the velocity is 0 as it is with uppermost objects. Then the distance is not being traveled at all. Ground is not being treaded forwards. Despite the graph starting from the point at 30m for instance. Therefore the object which moves the most is the lower left corner object moving at the constant speed 1m/s. Distance of that object is 10m traveled within 10s. The lower right corner object does also tread ground within 10s time. The object apparently moves forward as the orange graph indicates. 3m/10s = 0,3m/s. Distance of that object would be 0,3m/s x 10s = 3m distance travelled. 2) objects which move the least during 10 seconds are both the uppermost objects. Their velocities are 0. They do not tread any ground during 10 seconds time which are under review in the graph and the coordinates. [/QUOTE]
