No Need for “Force” of Gravity! Continued
Einstein’s theory is very mathematical and difficult to actually use.
Newton’s Theory is still very accurate for small gravitational fields and it is MUCH easier to use. Newton’s theory is still used for “everyday” problems”
- Falling Bodies, Projectiles, . . .
- Moon going around the Earth
- Planetary motion EXCEPT that very accurate descriptions require Einstein’s theory of General Relativity
General Relativity VERY important to understand the universe! More about this later!
