Homework Help Overview

The discussion revolves around calculating work done when lifting a toolbox on Earth compared to the Moon, focusing on the effects of gravitational differences on work calculations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between mass, gravitational force, and work done, with initial confusion about the calculations involved. Some question the impact of different gravitational forces on the work done.

Discussion Status

Participants have shared calculations for work done on both Earth and the Moon, with some expressing confidence in their results. There appears to be a collaborative effort to clarify the concepts involved, although no explicit consensus is reached.

Contextual Notes

There is mention of gravitational differences between Earth and the Moon, which is a key assumption in the calculations. The original poster indicates uncertainty in their approach, and hints have been provided to guide the discussion.

Homework Statement


Steve lifts a 5.0kg toolbox 0.5 meters off the ground. Compare the amount of work that would be done on Earth to the amount that would be done on the moon.

Homework Equations

The Attempt at a Solution


(no idea what i am doing)

work = force x displacement

x = (5/a) (.5) cos 9.8
 
Physics news on Phys.org
Hint: since the mass of moon is less than that of Earth , therefore its gravity is 1/6th of the gravity at earth.
 
Ok think i fixed it up a bit.
5 x g (planet) = f
w = f x .5
 
w Earth = 24.5 (units)
w moon = 4.08 (units)
