S

The distance S is affected by the car speed (call this V) when it hits the bottom of the ramp.

V, in turn, is determined by the ramp height H, because as the car rolls down the ramp, the potential energy at the top (mgH) is converted to kinetic energy at the bottom (1/2 * mV^2).

As H increases, so does V, and so does S.
 
we recently did an experiment where we got a sloping track, placed it on a table and we put a toy car a the top of the track and let it go. we realised the height of the of the track (steeper slope) affected the distance travelled by the car when it reached the table. why does H = height, affect S = distance?
