ROTATIONAL MOTION

On what fundamental laws is Newton's Second Law for extended bodies based?

• Only Newton’s First Law
• Only Newton’s Second Law
• Newton’s Second and Third Laws for particles
• Newton’s Law of Gravitation

How can the kinetic energy of a system of particles be decomposed?

• Into potential and thermal energy
• Into rotational and vibrational energy
• Into kinetic energy relative to the center of mass and kinetic energy of the center of mass
• Into linear and angular components

Why is knowledge of internal forces not required to determine the motion of the center of mass?

• Internal forces are always zero
• Internal forces act in the same direction
• Internal forces cancel out due to Newton’s Third Law
• Internal forces are too small to matter

How is angular momentum defined for a single particle?

• L = r + p
• L = r · p
• L = r × p
• L = p − r

What is the relationship between linear velocity and angular velocity for a point on a rotating rigid body?

• v = ω + r
• v = ω · r
• v = ω × r
• v = r/ω
