5. If a force acts perpendicular to an object's direction of motion, that force does zero work T/F: 6. The total energy of an isolated system is conserved only if there is no friction. T/F: 7. The wheels of a car are designed to have small moment of inertia T/F: (9260) 8. Isotopes are the same atoms with different mass T/F: 9. The weak and strong nuclear forces are fundamental forces T/F: 10. According to Newton's second law the net force applied to an object results in a change in motion. T/F: PART B: [35] 1. Newton's Laws a. Explain what gives rise to friction. Draw a picture in your response
