Momentum

Which one has more momentum a fast car or a slow car? 2. 1. Answer Now 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Which one has more momentum a large train or a shopping cart traveling at the same speed? Answer Now Large Train Shopping Cart 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Momentum In science, momentum = mass * velocity

Momentum Equation:p = m * v Units= kg x m/s

What is the momentum of a 75 kg speed skater moving forward at 16 m/s?

What is the momentum of a 48 What is the momentum of a 48.5 kg passenger on a train stopped on the tracks?

Collisions Law of Conservation of Momentum Momentum is always Transferred From One Moving Object to Another Object! Video

What would happen to a shopping cart sitting in the middle of a parking lot if a car bumped into it? Move Stay Stationary Answer Now 5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

What caused the shopping cart to move?

The law of conservation of momentum can be used to calculate the speed of the cart. Lets say the car has a mass of 1,400 kg and was traveling at a speed of 2.5 m/s. If all the momentum from the car was transferred to the 35 kg shopping cart, how fast would the cart be moving?

Collisions Conservation of Momentum Video Momentum is always conserved Therefore… Momentum can be trxfered from one moving object and cause another object to move Conservation of Momentum Video Conservation of Momentum Video 2
