Aim:
I am trying to find out what factors effect the distance a ball rollswhen released from the top of a ramp.

Units
Height of Ball from the ground
Height of Ramp
Distance ball rolls
Centimeters (cm)
Length of Ramp
Speed ball rolls
Surface of Ramp
Direction ball rolls
Surface of Floor
Weight of Marble
Size of Marble
Surface of Marble
Variables:
The height of the ramp will change the speed and distance the ballrolls because when the ramp is higher, the ball will be higher. Thehigher the ball is the more gravitational potential energy it has;therefore more energy will be transferred to kinetic energy. When thelength of the ramp is changed, so is its gradient, therefore the ballwill roll quicker and further. The surface of the ramp can causefriction on the ball; therefore kinetic energy is lost, so the ballslows down. Different surfaces of ramp will change the speed of theball and therefore also the distance it rolls. When the ball hasrolled off the ramp it will continue to roll on the floor, differentsurfaces of floor will result in different amounts of friction,changing the speed of the ball, and distance it rolls. The weight ofthe Marble will affect the distance it roll and also the speed atwhich it rolls at. This is because the heavier an object is the moregravitation potential energy it could have if it was lifted. The sizeof the marble may also be proportional to the weight, it will alsocause more friction because there will be more surface area of theramp touching the marble, this will slow it down and decrease itsrolling distance. The surface of the marble will cause friction withthe ramp and floor; different surfaces will cause different amounts of
