ROTATIONAL MOTION

Which rule is used to determine the direction of the vector product of two vectors using a screw analogy?

• Left-handed screw rule
• Clockwise rotation rule
• Right-handed screw rule
• Anti-screw rule

What is the direction of the vector resulting from the cross product of two vectors?

• Parallel to the first vector
• Parallel to the second vector
• Perpendicular to the plane containing the two vectors
• At a 45° angle to both vectors

Which of the following best defines the magnitude of the vector product of two vectors a and b?

• c = ab cosθ
• c = ab tanθ
• c = ab sinθ
• c = a + b

What is the significance of the constants c1, c2, c3 in momentum conservation?

• Initial positions
• Acceleration values
• They represent conserved momentum components in each direction
• Energy constants

How does the concept of center of mass apply to human motion?

• It increases strength
• It reduces weight
• It helps analyze balance and stability in walking or jumping
• It changes diet
