Gravity and Weight: How Do They Compare on Different Planets?

    Conceptual Weight
AI Thread Summary
The discussion focuses on comparing the weight of a 25kg object on Earth and Venus, where gravity is 8.8 m/s². The weight on Earth is calculated using the formula W = mg, resulting in a weight of 245 N. On Venus, the weight would be 220 N, indicating that Wvenus < Wearth. The angle of inclination and friction are mentioned but deemed irrelevant for the basic weight comparison. Understanding the relationship between gravity and weight is crucial for solving such problems.

"weight" problem (conceptual)

Homework Statement


an object has a mass of 25kg on Earth. If the same object is moved to an inclined plane in Venus, where the acceleration due to gravity is 8.8m/s^2, how does its weight compare to when it was still on earth??

a. Wvenus > Wearth
b. Wvenus = Wearth
c. Wvenus < Wearth
d. it depends on the angle of inclination of the inclined plane in venus
e. it depends on the friction between the plane and the object

Homework Equations


W = mg

The Attempt at a Solution


i'm not sure whether the angle of inclination is to be used here

i think it's C :p not sure though

What do you think? :smile:
 


i think it's C...?
 


Why? :smile:
 


ok last time i got in trouble for just giving an answer so i'll try my best not to give it away here. How do gravity and weight relate? w=mg . . . so what happens to weight after you you change gravity (on Earth its 9.8 and on venus its different), how are they related to one another? :)
 

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'

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...
