ROTATIONAL MOTION Quiz

• Only the number of forces
• The color of the body
• The net torque produced by the forces
• The temperature

• It is always zero
• Because the mass is large
• Because the velocity vector has a perpendicular component relative to the position vector
• Because time is infinite

• It causes pure rotation
• It has no effect
• It causes translational acceleration without rotation
• It destroys the body

• It makes planets stop
• It changes their mass
• It explains why planets sweep equal areas in equal times
• It causes eclipses

• They cause rotation
• They increase mass
• They do not affect the total force or torque on the body
• They change velocity
