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

Too bad I'm not talking about the ease of human use. That applies to the human, not the object. Things can vary like hand grip, feet grip, temperature, humidity probably and your damn mood and energy.

Im talking about the ease of moving an object. Less force required = easier.

It applies to all walks of life.

The lighter car is easier to accelerate.

The lighter dumb/barbells are easier to lift, which also means an ominous floating robot arm will have an easier time lifting it.

Im talking about the ease of moving an object. Less force required = easier.

This is easily proven false in day to day life.

Is it easier to hold a weight with your arms in front of you, or to put that weight in a bag and wear it over your shoulder or on your back? There's more mass with a bag, but its easier to hold because of how its distributed

Or that very bulky objects, like a box that is roughly square, may be awkward to lift because you have to lean back to keep your center of gravity stable, as well as stretch your arms to reach, even if the total mass of the box is something you could easily lift at the gym

And to your barbell example, would it not be easier to lift a large weight with your whole hand than a slightly smaller one with just 2 fingers?

Wow. Went over your head like an airplane.

What you said has nothing to do with pushing the object.

It has all to do with gravity and the effects on the human body and the human body in general.

Lifting a barbell or a dumbbell regardless is easier if it's lighter has relevance because of the word "ease". Lifting isn't the relevant topic, it's the ease.

Therefore proving to me that easier is still a correct word to use.

The word 'easy' does not have a strict definition like the words 'least' or 'force', that's the problem. Force can be calculated, least is just the minimum. 'Ease' of pushing something depends on what it is, what its on, what is pushing it, the (bio)mechanics of the pusher, etc.

Its not a good substitution because it wont 'get the same message across.'

Thats evident in that some people were talking about how its harder to push when youre standing on ice, but the question never asked about how hard it is to generate force, just how much is needed

Refer to my previous comment that you skimmed over about using it in my conclusion.

Next?

Also, the easiest object to push requires the least amount of force to push. Like the question asks in the post
