Document Summary

Presented the idea of force and the laws of motion. The rules that govern the motion in the heavens should also apply to earth . E. g. the car is going due north at 60 km/hour. Acceleration: the rate of change of velocity (speed or direction, or both) E. g. the car is changing speed from 0 km/h to 100 km/h in 9s. The car changed from going due north at 60 km/h to going due east at 60 km/h in 20s. If you add up the momentum of everything in a closed system you will find that no matter what happens, this momentum is conserved. If you add up the angular momentum of everything in a closed system you will find that no matter what happens, this momentum is conserved. There is a force between any two objects in the universe. The force is proportional to the product of the masses of each object.
