A few factors (the gradient/height of ramp, the mass of the object, friction, gravity, the energy act on the object or the length of object) can affect the final speed of an object at the end of the ramp.

Investigation A few factors (the gradient/height of ramp, the mass of the object, friction, gravity, the energy act on the object or the length of object) can affect the final speed of an object at the end of the ramp. Planning I am going to do my investigation on ' mass of the object' which I think it is one of the factors that will affect the final speed of an object at the end of the ramp because when gravitational potential energy equals to mass times gravity times height, so if mass is increased, the gravitational potential energy will increase in proportionally. I will do the experiment by adding weights on top of a wooden cart to increase the mass, and then I will time how long it takes to fall down from the ramp and calculate the final speed by: Diagram Weight add to the cart (grams) 0 100 200 300 400 Time (sec) 6'78 6'07 7'21 6'86 6'93 Weight add to the cart...
