[Physics] Position vs time graph with constant acceleration

Question

Wondering from the position vs time graph of an object moving with constant acceleration. How could you find the velocity? So the position vs time graph would be a parabola. I am thinking that the instantaneous velocity, $v_y$, may be found as the slope of the tangent to a displacement versus time graph at any point. Wondering if someone could help clarify this for me

Answer 1

For unidirectional uniform motion,average velocity,average speed,instantaneous velocity and instantaneous speed all are equal.

Things are not so complicated even if we are dealing with accelerated motion.Just find the point at which you want the instantaneous velocity and calculate its slope.it will give you instantaneous velocity.
