So h=1/2gt^2. I am having some trouble understanding this equation.
Here are my questions:
1. I know you get two completely different answers if you plug in a set value, but why can't you measure height of a free-falling object by multiplying the number of seconds^2 times 9.8m/s^2?
2. Is the coefficient 1/2 because you are compensating for the seconds^2?
3. Does the equation h=1/2gt^2 result because acceleration is the second derivative of position?
4. Why?
