Question

the velocity time graph of a body moving in a straight line under constant force

Answer 1

Answer:

Explanation:

The rate of change of quantity which is constant is always zero.

We know that    

dt ÷dV  =a

Now, the rate of change of quantity which is constant does not mean that it is zero,but its magnitude will be constant as the time will vary.

As we know that equation of line is written as y=mx+c

but when the value of constant c will be constant it will passes through origin and its magnitude will remain same.
