Newton's second law angular momentum
WitrynaMy textbook says that we can infer from Kepler's second law that angular momentum is conserved for a planet, and therefore gravity is a central force. Now I understand how constant angular momentum implies that gravity is a central force. However, I don't see how we know that angular momentum is conserved, based on Kepler's second law. http://panonclearance.com/write-an-equation-of-motion-including-the-rotational-acceleration
Newton's second law angular momentum
Did you know?
WitrynaFrom this you take just the units: Newton = kg . m/s^2, so now you know how to write Newton in basic units. bottom line - unit of the Moment of inertia: I=m.r^2, so unit is kg.m^2. So up you have: N.m = kg . m/s^2 (N) times meter = kg. m^2/s^2. down you have: kg.m^2. Kilograms will cancel out, also meters square (m^2) will cancel out.
