Decide whether each of these statements is True (T) or False
For a velocity−time graph:
(i) The distance travelled between two times is the area under the graph between the ordinates for those times.
(ii) The acceleration at any instant is the gradient of the graph at that time.
A) (i) T (ii) T
B) (i) T (ii) F
C) (i) F (ii) T
D) (i) F (ii) F

(i) True, because the area under a velocity-time graph represents the displacement (or distance if the velocity does not change direction) between two points in time. (ii) True, because the gradient (slope) of a velocity-time graph at any point gives the acceleration at that instant.
