What is the height of an equilateral triangle of side 0.5?

• 0.5√3
• 0.25√3
• 0.125√3
• √3

Why is the center of mass not at point B in the triangle example?

• Because B is too high
• Because mass at B is smallest
• Because other masses pull it toward the base
• Because gravity is weaker there

What is the geometric center of an equilateral triangle called?

• Circumcenter
• Incenter
• Centroid
• Orthocenter

How does unequal mass distribution affect the center of mass?

• It has no effect
• It shifts away from the heavier mass
• It shifts the center of mass toward the heavier mass
• It makes the center undefined

What is the position of point O in the equilateral triangle?

• (0, 0)
• (0.5, 0)
• (0.25, 0.25√3)
• (1, 1)
