Energy and Momentum | ||
#1 | This is how you can change the potential energy of an object | What is change the height? (or mass...) |
#2 | Marcquaja rolls a 6 kg bowling down the lane at 5 m/s and gets a strike. The ball has this much momentum. | What is 30 kg m/s? |
#3 | The total momentum of two objects with equal masses and speed moving towards each other | What is 0? |
#4 | Whenever we change the energy in an object, we do this to the object | What is do work? |
