... When we derive Newton’s equations of motion from a Lagrangian or Hamiltonian, the equations are invariant under time reversal, so that if x(t) is a solution, so is x(−t). If we add terms corresponding to damping or viscosity, the invariance is broken, and motions become obviously irreversible. Stran ...

... Resonance is the condition in which a time-dependent force can transmit large amounts of energy to an oscillation object, leading to a large amplitude motion. In the absence of damping, resonance occurs when the frequency of the force matches a natural frequency at which the object will oscillate. T ...

... This orientation of the long axis relative to the direction of the fluid is called angle of attack. Lift – an upward force of a fluid on an object associated with a greater force on the bottom surface of an object. This is associated with Bernoulli’s Principle, which states that the pressure in a mo ...
