Acceleration terms in a lagrangian are sometimes eliminated by substituting into the lagrangian the equations of motion which were obtained from the lagrangian. We show that, in general this is an incorrect procedure. In addition, we present a new correct procedure, which we call the method of ...

u.(t) is the velocity of the mass at time (t), and it is equal to the first derivative of u with respect to time In static studies, velocity and acceleration are so small that they can be neglected and F and u are not functions of time. The above equation reduces to: F=ku. ...

Kinematics Equations Of Motion The equations we’re discussing are fundamental to understanding motion, specifically when dealing with constant or uniform acceleration. Known as the equations of motion, they form the cornerstone of kinematics, a branch of classical mechanics that describes the motion of...

Figure 1. Kinematic equations can help us describe and predict the motion of moving objects such as these kayaks racing in Newbury, England. (credit: Barry Skeates, Flickr) We might know that the greater the acceleration of, say, a car moving away from a stop sign, the gre...
(4) Compute the leading part of the equation. Hopefully, only terms that involve the acceleration will be dominant. This is the "inertial" part. (5) Compute the quadratic part of the equation. This is the agent of the "force". (6) Equate for each singularity, the highest order terms ...
