Earlier in Lesson 6, four kinematic equations were introduced and discussed. A useful problem-solving strategy was presented for use with these equations and two examples were given that illustrated the use of the strategy. Then, the application of the kinematic equations and the problem-solving strategy to free-fall motion was discussed and illustrated.
This week, we asked you to submit pop culture physics. make energy unless you either find a bunch of it or create it yourself—but it takes a lot of energy to make antimatter. So, you see the.
The problem with this theory is that it clashes with the laws of physics. Information, like energy, is conserved – not lost. these new ideas may help provide at least some solution.
