Measuring Acceleration Due to Gravity: Experiments & Graphs

AI Thread Summary
The discussion focuses on two physics experiments designed to measure acceleration due to gravity. In the free fall experiment, a ball is dropped from different heights, and the time taken is recorded to apply the formula s=ut + 0.5at^2, raising questions about what to plot on the graph. Suggestions include plotting height against time and considering whether additional heights are necessary for more data. The second experiment involves a trolley and pulley system with varying masses, prompting inquiries about how to graph the results and whether multiple graphs are needed. Overall, clarity on graphing methods and the relationship between variables and constants in the experiments is sought.

Hey, i got to do 2 experiements for physics to measure acceleraetion due to gravity,
i did free fall experiment, dropping a ball from a certain hieght and measuring time n using the s=ut +.5 a t^2 forumula to get a
and i need to graph this but i do not know what the two things i shot plot
maybe the hieght and time?
also i droped it from 2 hieghts should i need to do it more?
do i need to plot 2 graphs?

also the second experiment i did was da 1 where u have the trolley n ticky tape timer n the tape is attached to da trolley n a string on other side is attached to the trolley and the string is over a pulley n attached to a mass
i did it with 3 different mass and repeated it twice with each mass
so how would i graph this experiment?, do i need three graphs?, please help
thanks.

concerning the graph, you should think, in the s=ut+0.5at^2 equation, which are the constants and which are the variables?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
