Q:using a plumb line and a string measure the vertical distance h, the ball (steel ball) must drop from the bottom end of the ramp in order to land in an empty soup can on the floor.
1)what may cause a ball to miss the target?
2)you probably noticed that the range of the ball increases in direct proportion to the speed at which it left the ramp. the speed depends on the release point of the ball on the ramp. what roles do you think air resistance had in this experiment?
3)should the height of the can be taken into account when measuring the vertical distances h?

1)what may cause a ball to miss the target?
*Variation in distance. Caused by ramp speed. Possibly launch angle variations caused by ball imperfections and minor variations of position on launch ramp.
2)you probably noticed that the range of the ball increases in direct proportion to the speed at which it left the ramp. the speed depends on the release point of the ball on the ramp. what roles do you think air resistance had in this experiment?
* Minor. The fact that the range of the ball increased directly with speed indicates that air resistance was not causing an apreciable decrease in velocity.
3)should the height of the can be taken into account when measuring the vertical distances h?
*Yes. The ball enters the can at the can's tallest point which, in turn, determines the distance the ball traveled.

Hi :-) As you increase the voltage the current also increases causing the filament in the light bulb to get hot, the current starts to even out because the filament has already become hot enought and can't get any hotter, the resistance also increase because when you use the formula V=IR to get R we use R= V/I and if the voltage is still increasing by a large amount but the current is not then you are basically getting a higher resistance because the the current would more or less stay the same but you are dividing a bigger voltage with the same current so it is bigger, It is the same for the smaller current, the resistance and voltage is more or less proportional because as you increase V, R has to increase to maintain the correct current through the lighbulb, I=V/R if the voltage is rising and the resistance is aswell then I would not change because both V and R are rising :-) If you wanna know anything else email me ;-) I'm from the UK aswell :-)
