Question

1. Which has more momentum, a heavy truck moving at 30 km/h or a light truck moving at 30 km/h? A. heavy truck B. light truck C. Both have the same momentum D. Cannot be determined. 2. In certain martial arts, people practice breaking a piece of wood with the side of their bare hand. Use your understanding of impulse to explain how this can be done without injury to the hand. A. Given the same change in momentum, when the time interval is smaller the impact force is bigger. B. Given the same change in momentum, when the time interval is bigger the impact force is bigger. C. Given the same change in momentum, when the time interval is smaller the impact force is smaller. D. Given the same change in momentum, when the time interval is bigger the impact force is smaller. 3. Which statement is NOT true about impulse? A. The kg·m/s is equivalent to the units on impulse. B. An object which experiences a net impulse will definitely experience a momentum change. C. In a collision, the net impulse experienced by an object is equal to its momentum change. D. A force of 10 N acting for 0.1 seconds would provide an equivalent impulse as a force of 5 N acting for 2.0 seconds. 4. Which statement is NOT true about momentum? A. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. B. Less massive object can never have more momentum than a more massive object. C. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have the greatest momentum. D. An object which is moving at a constant speed has momentum. 5. Which is a necessary condition for the total momentum of a system to be conserved? A. Kinetic energy must not change. B. No external force is present. C. An object must be at rest. D. Only the force of gravity acts on the system.
