Newton’s Laws continued
- Key ingredient is forces - must be specified
- Examples: Falling bodies (F = mg) due to gravity; Circular motion (a = v2/R) implies a centripetal force
- Universal Law of Gravity (F = G Mm/R2 )
- Apple, Moon, Planets obey the same laws!
- Derived Kepler's laws from more fundamental principles.
- Unites the motion of earthly and heavenly bodies. Profound impact upon our view of the universe!
