Two objects of equal weights placed on a glass surface and a wooden
surface.

A better experiment would be to have a ramp with different surfaces (such as sandpaper, wood, glass, etc.) and measure the angle at which an object starts to slide down the ramp. This would allow for a more accurate measurement of friction on different surfaces. Furthermore, it would be better to have multiple trials for each surface and calculate an average angle to reduce the potential for errors.
