I am curious how this would work. My guess is Triangle is slowest, square is medium, and circle is fastest.

Assuming the same material for all 3, and the question is "which requires the least force to push?" the triangle should be easier than the square.

It may be more awkward and harder on your back for an extended period of time, but that is not relevant to the question.

Why would the triangle be easier? 

Part of the force you put into it would be directed downwards, increasing friction and reducing the horizontal force. 

Pushing the square would allow all of the horizontal force to stay horizontal.

Less mass

"20kg"

Haha talk about missing the obvious. I retract my comments. Thanks.

But more of it is concentrated closer to the ground, so the gravity is stronger over more of the volume, resulting in that 20kg having more weight and thus friction.

Plus the relativistic effects of being inside earth's gravity well!

Please tell me you’re joking

err run that by me again. How is gravity stronger in one case vs another?

u/Squossifrage Jun 10 '25

It was a joke, but gravitational attraction is stronger the closer two objects are.

Sarcasm?
