The graph shows the v eug 5 oz(;(y9o lgum.oariation 5jroi.k2k db : ,sv5kpof velocity v with time t of a car.
Which of the following can be deduced from the graph?
I. Displacement
II. Acceleration
III. Change in velocity
A. only I
B. only II
C. only I and II
D. all of them
参考答案: D
本题详细解析:
Change in velocity can be read from the vertical axis, the area under the line gives the displacement and acceleration can be deduced from the gradient of the graph. Therefore, the answer is D.
