Momentum 4.5 / 5 based on 4 ratings ? PhysicsPhysicsGCSEEdexcel Created by: science_10x1Created on: 27-11-17 18:05 What is the equation for momentum? Momentum = Mass X Velocity 1 of 13 What is momentum measured in? Kg m/s 2 of 13 If an object has the greater mass or velocity what does this mean for the momentum? The more momentum the object has. 3 of 13 Is momentum a vector or scalar quatntity? Vector. It has size and direction. 4 of 13 What momentum does a 50kg cheetahs that is running at 60 m/s have? 50x60= 3000kg m/s 5 of 13 a boy has a mass of 30kg and a momentum of 75kg m/s. Calculate his velocity. 75➗30= 2.5 m/s 6 of 13 True or false, total momentum before = total momentum after True 7 of 13 What is a closed system? Another way of saying no external forces act 8 of 13 Calculate the momentum of a 60kg woman running at 3m/s 180 kg m/s 9 of 13 CHANGES IN MOMENTUM CHANGES IN MOMENTUM 10 of 13 What do forces cause? Changes in momentum 11 of 13 What so the equation for force? Force(N) = change in momentum(kg m/s) / time(s) 12 of 13 Calculate the force a tennis racket needs to apply to a 58g tennis ball to accelerate it from rest to 34m/s in 11.6ms. 170N 13 of 13
