Question

plot the velocity- time graph showing 1a and 2a. How is distance calculated from velocity time graph?(a here stands for acceleration)

Answer 1

well the distance can be calculated by calculating the area under the curve if velocity and time graph .
The graph of the body with high acceleration will have more slope than those with low acceleration here 2a has more acceleration than 1a so the slope of 2a will be greater than that of 1a and if its constant acceleration then the the curve will be a straight line if the value of acceleration a is 0 the the curve will be parallel to X axis 
Hope this helped you
