The aim of this experiment is to verify the relationship amongst T and the good deal of the hanging destiny MH.
The hypothesis has been theorize that the time squared go forth be inversely proportionate to the mass of the hanging mass MH. This is because as the hanging mass increases, more force has to be applied in regularize to keep the length of get between the piling and the icing tube at 50 cm. Therefore the angle volition be swinging in a faster consider in comparison to when MH is lighter; less force will be required to keep the length of the string at 50 cm.
Equipment
Glass Tube
2 x 100g of hanging mass increasing at intervals of 10 g
Piece of string
Rubber Bung
Stopwatch
Method
1. stick to 20g of hanging mass to the system
2.Swing the bung until length of the string reaches 50 cm from the bung to the glass tube and the bung is parallel angle to the ground
3.Start the stopwatch and time 10 full circular rotations of the bung with the length at 50cm
4. buy up 4 more times before adding another 20 grams to the system
Variables
Independent variable: Mass of hanging mass (20 200g at intervals of 20g)
Dependent variable: date taken in seconds for 10 full rotations
Control: mass of the bung, length of the string from bung to glass tube, angle of rotation, and gravity.
