AI Thread Summary
A user seeks a toy to demonstrate concepts of acceleration due to gravity, net force, mass, and weight, considering a tennis ball as a potential option. Respondents suggest that many toys could illustrate the first, third, and fourth concepts effectively. The discussion emphasizes the need for clarification on the term "net force" and its implications. Participants encourage deeper understanding of the concepts involved in the project. Overall, the conversation focuses on finding suitable toys while enhancing comprehension of fundamental physics principles.

I need to find a toy that demonstrates the following terms:

acceleration due to gravity
net force
mass
weight


it can be any sort of toy, i was thinking a tennis ball or something of that sort?

Welcome to the PF.

Just about anything would demonstrate the 1st, 3rd and 4th, I would think. Can you explain what you have learned about "net force" so far? What does that term imply?
 

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...
