Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
The center of mass of a system lies at the geometric center of the object.
- True
- False
💡 Hint: Consider cases where mass is unevenly distributed.
Question 2
What formula is used to calculate the center of mass for three particles?
- X_{CM} = (m1*x1 + m2*x2 + m3*x3)/(m1 + m2 + m3)
- X_{CM} = (m1 + m2 + m3)/(x1 + x2 + x3)
- X_{CM} = (x1 + x2 + x3)/(3)
- X_{CM} = m1*x1 + m2*x2 + m3*x3
💡 Hint: Think of how to balance masses.
