1. The center of mass of an object is the point where:
All of its mass is concentrated.
The object is perfectly balanced.
The sum of all external forces is zero.
Its velocity is constant.
2. For a uniform object, the center of mass is typically located at its:

Surface
Geometric center
Any arbitrary point
3. The center of mass is a unique point for an object or system of particles where the of the system is considered to act.
4. For an object to be in stable equilibrium, its center of mass must be its base of support.
5. Explain the difference between center of mass and center of gravity. Under what conditions are they the same?
6. Three masses are placed along the x-axis: m1 = 2 kg at x = 1 m, m2 = 4 kg at x = 3 m, and m3 = 3 kg at x = 5 m. Calculate the position of the center of mass for this system.
7. The center of mass of an object must always be located within the physical boundaries of the object itself.
