The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...

The oldest mathematics journal in the Western Hemisphere in continuous publication, the American Journal of Mathematics ranks as one of the most respected and celebrated journals in its field.

In this video, we introduce the fundamentals of kinematics in 2D, focusing on projectile motion. Learn how to break down the horizontal and vertical components of motion, apply key equations, and ...

A red and a blue snooker ball both have a mass of 160 g. They collide with speeds and directions as shown in this diagram. The following steps show you how to calculate the velocity of the red ball ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...

You might recall the classical experiment in Freshman physics of two pendulums that are coupled together wtih a soft spring. This pendulum system is another example of a system that exhibits beating ...
