... accelerate faster; this is because we are measuring the time it takes for the trolley to get to the bottom of the ramp; and the changes in acceleration. Every 2 dimensional movement (ignoring the fact the trolley can go side to side) has 2 directions: X and Y. In this experiment Y will be gravity and X will be determined by the angle of the ramp. If the ramp is steeper than the net movement of the trolley will be forwards and downwards; and as the ramp will be steeper this will allow the Y force of gravity to pull the object quicker; as the area of the ramp will be cleared in a quicker time. I have also noticed that the mass of the object does not effect the acceleration; this is because if an object has a higher mass then gravity will need more force to pull it whilst ...
