The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

Learn how to calculate the vector change in momentum of a bouncing ball in this physics tutorial! This video explains the concepts of momentum, direction, and collisions step by step, making it easy ...

Learn how physics and programming come together in this Python simulation of elastic collisions! In this tutorial, we explore the fundamental principles of momentum and energy conservation while ...

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It ...

(Nanowerk News) Thanks to new technology, it is possible to retain individual atoms, move them in a targeted manner or change their condition. Kaiserslautern physicists also work with this system. In ...
