Answer true or false:
If the average velocity of an object during the time interval from $t$ to $t + ∆t$ is denoted as: $$\frac{s(t + ∆t) - s(t)}{∆t}$$
then the instantaneous velocity can be estimated by making $∆t$ as close to zero as possible.
My answer: True. My reasoning.
Is this correct?
Yes, the limit of the average velocity $$\frac{s(t + ∆t) - s(t)}{∆t}$$
as ∆t approaches zero is exactly what is called instantaneous velocity.
