Could someone please explain in detail the effect of height on the time an object takes to fall?
It takes longer to fall because of the increasing height.
The air resistance will be the same as long as the shape of the robocopter stays the same, so that would not be a factor. The increase in displacement (height/distance) each time is the reason that the time to fall increases with each trial.
The following equation can illustrate this.
Because the motion is downward, both the displacement and acceleration are negative.
Rearrange the equation to solve for
Multiply both sides by
Divide both sides by
Plug in the known variables.
Take the square root of both sides.
Since both the displacement and acceleration are negative, they cancel each other when divided, so the result is positive.
Redo the equation when the displacement (height) is
Now redo the equation with the displacement of
As you can see, as the height displacement (height) increases, the longer it takes for the robocopter to fall.
