Kinematics Equations Of Motion The equations we’re discussing are fundamental to understanding motion, specifically when dealing with constant or uniform acceleration. Known as theequations of motion, they form the cornerstone of kinematics, a branch of classical mechanics that describes the motion of ...
The equations of motion describing the flow in a fluid are based on the three laws of conservation of mass, momentum and energy. For a detailed formulation of these equations, one of the standard works in fluid mechanics should be studied (see literature list). Here we limit ourselves to a...
Kinematics is the study of motion, without reference to the forces that cause the motion. In kinematics, there are five important quantities: displacement (change in position), initial velocity, final velocity, acceleration, and time. Initial velocity is how fast an object is moving at t= 0....
In this activity, we systematize some results on the study of the equations of a motion of dynamically symmetric four-dimensional fixed rigid bodies-pendulums located in a nonconservative force fields. The form of these equations is taken from the dynamics of real fixed rigid bodies placed in ...

Equations in physics are expressions of equality between related quantities. When all but one of the quantities are known, they can be plugged into an equation and used to find unknown quantities. For mechanics (motion and forces) there are a few basic equations t...
Motion of level sets by mean curvature. I We construct a unique weak solution of the nonlinear PDE which asserts each level set evolves in time according to its mean curvature. This weak solution allows us then to define for any compact set 螕0 a unique generalized motion by mea... LC ...
Luckily, when we use the equations of motion, we assume air resistance is insignificant enough to ignore. The second assumption we can make when using these equations involves acceleration. We already know that acceleration is constant for kinematics problems, which means that the average ...
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...
A very wide range of physical processes lead to wave motion, where signals are propagated through a medium in space and time, normally with little or no permanent movement of the medium itself. The shape of the signals may undergo changes as they travel through matter, but usually not so mu...
