ROTATIONAL MOTION

In a system with no external forces, how does the center of mass velocity behave?

• Increasing
• Decreasing
• Oscillating
• Constant

What is the primary reason for using the center of mass frame in physics?

• To increase velocity
• To simplify the equations of motion
• To measure temperature
• To change reference

How does the center of mass motion affect the observed paths of binary stars?

• It cancels orbital motion
• It adds uniform motion to orbital paths
• It stops the stars
• It changes mass

What is the geometric arrangement of two stars in a binary system in CM frame?

• Adjacent
• Random
• Diametrically opposite
• Overlapping

In the center of mass frame, what is the total momentum of a decaying particle?

• Maximum
• Minimum
• Zero
• Equal to mc
