Questions NCERT Question 9 - What is the momentum of an object of mass m, moving with a velocity v? (a) (mv) 2 (b) mv 2 (c) ½ mv 2 (d) mv View Answer NCERT Question 13 - A hockey ball of mass 200 g travelling at 10 m s–1 is struck by a hockey stick so as to return it along its original path with a velocity at 5 m s–1. Calculate the magnitude of change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick. View Answer NCERT Question 18 - How much ... Momentum as a Vector Quantity Momentum is a vector quantity. As discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling ball. It is not enough to say that the ball has 10 kg•m/s of momentum ; the momentum of the ball is not fully described until information about ... Momentum is the product of mass and velocity of an object. Learn how to calculate momentum , impulse, and change in momentum , and see how they relate to force and collision. Momentum , product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
