Period 2 Question 2

A torque that is generated by a single force is NOT zero when The force is perpendicular to the lever arm The force is parallel to the lever arm The force is not zero the support of the force goes through the center of rotation

Period 3 Question 1

The astronauts in the space station are weightless because of the outward pointing centripetal force the normal force is equal to the gravitational attractive force their acceleration = gravitational attractive force / their mass they are wearing a spacesuit their kinetic energy is equal to their potential energy
