WEEK 6: FORCE MASS AND ACCELERATION
... In this lab you will continue to develop the first two of Newton’s famous laws of motion. You will do this by combining careful definitions of force and mass with observations of the mathematical relationships among these quantities and acceleration. You have seen that the acceleration of an object ...

the Lagrangian formulation
... Which is also a mess! But it’s a mess that was much simpler to derive. Moreover, we don’t need to do any more work to get the second equation for µ: the symmetry of the Lagrangian means that it must be the same as (2.26) with λ ↔ µ interchanged. 2.3 Constraints and Generalised Coordinates Now we tur ...

3.Momentum
... • The Total Momentum of a system equals the vector sum of the momenta of all the objects in the system: • PTotal System = P1 + P2 (for a system of two objects) • Also called the “Net Momentum”: PNET • EXAMPLES: – We have two cars, each with mass: m=6 kg. One travels at 20m/s East and the other at 20 ...

The Graviton Equations
... Einstein's theory of General Relativity suggests that gravity is caused by bending space-time. The graviton equation proposes a mechanism but it has not yet been proved. The equations are not gravity. They only attempt to calculate the force between two objects. The apple dropping on Newton is an ex ...

We’ll just state that airplanes must fly by shoving air down. The downward force on the air is matched by the upward force on the plane, in level flight. ...
