Physics
Which concept allows a complex system of objects to be simplified into a single equivalent object?
How do you calculate the total mass of a system?
Find the center of mass along the x-axis for masses: 2 kg at x=2, 4 kg at x=4, and 6 kg at x=6.
Estimate the center of mass of a system with masses distributed at coordinates (2,3), (4,5), and (6,7) with masses 1 kg, 2 kg, and 3 kg respectively.
Why might the center of mass and center of gravity differ?
