What causes mice to become lighter?
For those with limited physics understanding, the mass, kg, does not influence the speed of the object. What really counts is the friction between the mouse and the surface. If you have a 1kg heavy mouse and a 10gram mouse on the same surface, the force needed to move them is identical. We apply a horizontal force while the weight acts downward, so these forces never affect each other.
But adding more weight increases resistance to movement, and it also requires greater effort overall. Or are you asking whether placing a one-ton rock versus a ten-kilogram rock on the same table would make them move equally easily? Probably not—under normal conditions, heavier objects resist motion more than lighter ones.
It's simpler and quicker to shift a lighter mouse.
From stillness, lifting a heavy item requires greater effort compared to a lighter one.
In the same way, halting a heavier object demands more strength, especially since it's already in motion.
The force involved is not identical.
But adding more weight increases resistance to the surface, and it also requires greater effort to shift that weight overall. Or are you asking whether placing a 1-ton rock on a table and a 10 kg rock on the same table would allow for equal ease of movement? You might think, if we ignore gravity, assume a perfectly smooth surface and a vacuum, then the physics of moving a heavy versus a light mouse would be identical. But on Earth with its gravitational pull, that mass does indeed play a role.
