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 ...

It's impossible to talk about football these days without talking about the problem of big hits. The giant dramatic collisions between players moving at high speed are at once one of the great ...

The questions in this quiz are suitable for GCSE physics students studying momentum calculations, conservation of momentum and force and momentum. If you struggled with the quiz, don't panic - we've ...

The vibrations of atoms in a crystal generate one type of rotation, an intrinsic spin-like trait called angular momentum. For ...
