Greater influence on movement: Mass OR Gradient?

Click For Summary

Homework Help Overview

The discussion revolves around understanding the factors influencing the rate of movement of an object down a slope, specifically comparing the effects of the gradient of the slope and the mass of the object. The context includes a scenario with a constant distance of 80cm and a specific example involving a small glass marble weighing 3 grams.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are exploring the relationship between mass and slope gradient in determining movement rate. Questions about the net force acting on the object and its implications for acceleration are raised. Some participants are questioning the assumptions regarding mass and acceleration, particularly in extreme cases like a 90-degree slope.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the influence of mass versus slope gradient. Some have provided initial equations related to acceleration and net force, while others are asking for further details and exploring general principles without reaching a consensus.

Contextual Notes

Participants are working with limited information, particularly regarding the specifics of the net force acting on the object. There is an emphasis on understanding the underlying physics rather than deriving a definitive answer.

1. Which, if any, has the greater influence on rate of movement down a slope with a constant distance of 80cm: the gradient of the slope or the mass of the object moving down the slope?

2. acceleration = net force / mass

3. If the slope is 90 degrees, the rate of movement of falling objects with different masses would be the same because the acceleration of an object is inversely proportional to its mass.

Am I on the right track here? Any assistance will be appreciated. Thanks in advance

and how big is that net force?

Thanks for your reply willem2. The object moving down the slope (a small glass marble) weighs 3 grammes. This is all the info I have, hope this answers your question.
 
I was wondering generally speaking, what would have a greater influence on movement of a object, its mass or the slope?
