Astudent divides several cubes into two groups, based on whether or not each cube can float in water. what property is the student using to classify the cubes?

Density is the amount of mass and volume in an object. the more mass and more volume in an object, the heavier the object is. the students would use density to seperate the cubes from one another into different groups.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
