IBDP Tutor - Physics : Motion ( What represent speed in displacement-time graph ?) Tangent is given.

IBDP Tutor - Physics : Motion

The graph shows how the displacement of an object varies with time. The tangent to the curve at time, t1 is also shown.

Which of the following gives the speed of the object at point P?

[liusweeyi]

+1, the answer is velocity is tangent.

[hakkyuulay]

well, this is because speed is the magnitude of velocity vector.

[arimann]

tangent is technically the magnitude of velocity .

[shazzuzaima]

to find speed in displacement-time graph, use the gradient because velocity is the slope of that graph.
