WebSo in the dot product you multiply two vectors and you end up with a scalar value. Let me show you a couple of examples just in case this was a little bit too abstract. So let's say that we take the dot product of the vector 2, 5 and we're going to dot that with the vector 7, 1. Well, this is just going to be equal to 2 times 7 plus 5 times 1 ... WebApr 5, 2024 · In physics, and in science in general, energy is typically defined as the ability to do work. Work, in turn, is the integral (along the appropriate path) of the dot product of the force and displacement vectors. Or it’s the subject of a Dolly Parton song -- two distinct contexts, two distinct meanings.
