Understanding Center of Mass

What is the center of mass of an object?

• The point where the object's volume is largest

• The point where the object's mass is concentrated

• The point where the object's surface area is largest

• The point where the object's color is most intense

How does the center of mass behave in projectile motion?

• It follows a parabolic path

• It moves in a circular path

• It remains stationary

• It follows a straight line

What is the classic method to find the center of mass of an irregular object?

• Hanging it from different points and drawing lines

• Calculating its surface area

• Weighing it on a scale

• Measuring its volume

In a two-body system, where is the common center of mass located?

• Closer to the less massive body

• Closer to the more massive body

• Outside the line connecting the two bodies

• Exactly halfway between the two bodies

Why is the center of mass of the Earth-Sun system close to the Sun?

• Because the Earth is closer to the Sun

• Because they are the same size

• Because the Sun is much larger

• Because the Earth is much larger
