Homework Help Overview

The discussion revolves around a conceptual problem comparing the weight of an object on Earth and Venus, focusing on the effects of different gravitational accelerations. The original poster presents a scenario involving an object with a specified mass and questions how its weight changes when moved to an inclined plane on Venus.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants express uncertainty about the relevance of the angle of inclination and friction in determining weight. They also explore the relationship between gravity and weight using the equation W = mg, questioning how changes in gravitational acceleration affect weight.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts on the correct answer and engaging in a dialogue about the underlying concepts. Some guidance is offered regarding the relationship between gravity and weight, but no consensus has been reached.

Contextual Notes

Participants are navigating the implications of different gravitational forces and the conditions of the inclined plane, indicating that assumptions about friction and inclination may influence their reasoning.

"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? :)
