Learn how symmetry leads to conservation of momentum, angular momentum, and energy.
Reducing a two-body system (like Earth and Sun) to a one-body problem using Reduced Mass .
Newtonian mechanics gets messy with "constraints" (e.g., a bead on a wire). This motivates the next step. 2. Lagrangian Mechanics (The Energy Approach) Instead of forces, we use Scalar Energy . The Lagrangian ( ): Defined as (Kinetic minus Potential energy).
Deriving why orbits are ellipses and how areas are swept out equally in time. 6. Rigid Body Dynamics Moving beyond point particles.
