Momentum Notes * Momentum = Units: Momentum Analysis Chris Johnson Brian Urlacher Weight 191 lbs Mass 86.6 kg Time 4.24 s Speed 9.43 m/s 258 lbs 117 kg 4.5 s 8.89 m/s 317lbs 143.7 kg 4.9 S 8.16 m/s Jake Long Who do you think will have the greatest momentum? Momentum 1) A steel ball whose mass is 2.0 kg is rolling at a rate of 3.0 m/s. What is its momentum? givens Unknown Formula and solve: 2) A go-cart is traveling at a speed of 15 m/s and has a mass of 100 kg for both the cart and driver. What is the momentum of the cart and driver? givens Unknown Formula and solve: 3) Who has the greater momentum? A 140 kg lineman running 6 km/hr or a 100 kg quarterback running at 12 km/hr? Show work Momentum Worksheet #1 True or False? _______1. Momentum is not equal to the mass of an object divided by its velocity. _______2. The momentum of an object can change. _______3. Two objects with the same mass will always have the same momentum. _______4. All moving objects don’t have momentum. _______5. When an object speeds up, it gains momentum. _______6. Objects with different masses can’t have the same momentum. _______7. Direction does not matter when you are measuring momentum. _______8. Momentum can be transferred from one object to another. _______9. When objects collide, some momentum is lost. _______10. A tiny bullet can have more momentum than a huge truck. Given the following data, solve for the missing value. Object Mass (kg) Velocity (m/s) Momentum (kg-m/s) Bird .04 19 Football player 100 10 Skier 60 1200 Bullet .004 24 Frog .9 12 Meteorite .1 1,000 .14 30 Baseball Wagon Satellite 3 3,00 .76 6 240000 1. List the objects from least momentum to greatest. 2. Does the order of these objects surprise you? Why or why not? 3. Do you think that these objects would always be placed in the same order according to momentum?
