Read each question carefully and provide your answers in the space provided. Show all your work for calculation problems.
1. What is the center of mass of an object?
The geometric center of the object.
The point where all the mass of the object is concentrated.
The point where the object can be balanced.
Both b and c.
2. For a uniform object, where is its center of mass located?
At its edge.
At its geometric center.
Outside the object.
It varies depending on the material.
3. The center of mass is a unique point where the weighted average of the of all the particles in an object lies.
4. For an object to be in stable equilibrium, its center of mass must be directly above its .
5. Explain the difference between center of mass and center of gravity. Under what conditions are they considered the same?
6. Consider a system of two masses: m1 = 2 kg located at (1, 0) m and m2 = 3 kg located at (4, 0) m. Calculate the x-coordinate of the center of mass for this system.
7. A uniform rod of length 5 m has its center of mass at its geometric center. If a 1 kg mass is placed at one end of the rod, where would the new center of mass of the system (rod + mass) be located relative to the original center of mass of the rod?
8. The center of mass of an object must always be located within the physical boundaries of the object.
