We solve problems pertaining to the Conservation of Momentum using various scenarios. In this Closer Look segment on conservation of momentum, we solve problems pertaining to the conservation of ...

"Learn how to simulate elastic collisions using Python in this hands-on physics tutorial! In this video, we’ll walk through the code to model collisions between two objects, showing how to apply the ...

There are analogous notions once we include relativity or quantum mechanics, but for our present purposes the version that Galileo and Newton would have recognized is good enough: in any interaction ...

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, ...

Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...
