The Lagrangian Method
... S is called the action. It is a quantity with the dimensions of (Energy) × (Time). S depends on L, and L in turn depends on the function x(t) via eq. (6.1).4 Given any function x(t), we can produce the quantity S. We’ll just deal with one coordinate, x, for now. Integrals like the one in eq. (6.14) ...

Dynamics – Free Fall, Apparent Weight, and Friction (Honors)
... In the vertical, you see the normal force, N, and the weight, W, which are equal and opposite. Thus there is no vertical acceleration by the cart, and there won’t ever be with a level, indestructible track. (Fn and W are drawn half scale as Fn /2 and W/2 because they’re so large and tend to go off t ...

momentum
... The amount of momentum which an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. In other words: The size of the momentum is equal to the mass of the object multiplied by the size of the object's velocity. ...

Center of mass
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. Calculations in mechanics are often simplified when formulated with respect to the center of mass.In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.
