If the initial velocity of the glider or ball was not zero, how would your experimental value of g compare with the value you obtained by assuming the initial velocity was zero? For instance, suppose you accidentally gave the object a slight shove down the incline at the starting point. Would your calculated value for g be larger or smaller?
Since we are assuming the initial velocity to be zero in our method of calculation,
any initial velocity of the glider or ball down the track would lead to a lower value
for the acceleration calculated in this way.
