Classical mechanics

device that measures mass flow rate of a fluid traveling through a tube

theorem

assembly of rigid bodies connected by joints to provide constrained motion that is the mathematical model for a mechanical system

frame of reference

invariance with respect to addition of a constant vector to a coordinate system

thumb|A rattleback in action A rattleback is a semi-ellipsoidal top which will rotate on its axis in a preferred direction. If spun in the opposite direction, it becomes unstable, "rattles" to a stop and reverses its spin to the preferred direction.

In Fig. P is the point of rotation

The newton-second (also newton second; symbol: N⋅s or N s) is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second.

thumb|Potential energy of a diatomic molecule as a function of [[atomic spacing. When the molecules are too close or too far away, they experience a restoring force back towards u0. (Imagine a marble rolling back and forth in the depression.) The blue curve is close in shape to the molecule's actual potential well, while the red parabola is a good approximation for small oscillations. The red approximation treats the molecule as a harmonic oscillator, because the restoring force, ''-V'(u), is linear with respect to the displacement u''. ]]

A mechanical system is scleronomous if the equations of constraints do not contain the time as an explicit variable and the equation of constraints can be described by generalized coordinates. Such constraints are called scleronomic constraints. The opposite of scleronomous is rheonomous.
