Question
a volleyball is spiked Which one of the following statements concerning momentum is true? Momentum is a force. Momentum is a scalar quantity. The SI unit of momentum is kg middot m^2/s. The momentum of an object is always positive. Momentum and impulse arc measured in the same units. As a tile falls from the roof of a building to the ground its momentum is conserved. True False In an INELASTIC collision between two objects the momentum of each object is conserved. the kinetic energy of each object is conserved. the momentum of the system is conserved but the kinetic energy of the system is not conserved. both the momentum and the kinetic energy of the system are conserved. the kinetic energy of the system is conserved, but the momentum of the system is not conserved. Which one of the following statements concerning momentum is true? Momentum is a force. Momentum is a scalar quantity. The SI unit of momentum is kg middot m^2/s. The momentum of an object is always positive. Momentum and impulse are measured in the same units.Explanation / Answer
1. E) Momentum and Impulse are measured in the same units. (Kg.m/sec)
2. Since accelaration is involved the momentum is not conserved. So the answer is (B) False.
3. In Inelastic collision between two objects (C) the momentum of the system is conserved but the Kinetic energy of the system is not consevered. Since the energy is lost in case of inelastic collision.
4. E) Momentum and Impulse are measured in the same units. (Kg.m/sec)
