WebAlthough speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. WebWe use the symbols ⊥ and ∥ to represent perpendicular and parallel, respectively. This choice of axes simplifies this type of problem, because there is no motion perpendicular to the slope and because friction is always parallel to the surface between two objects.

WebOne of the basic vector operations is addition. In general, whenever we add two vectors, we add their corresponding components: (a, b, c) + (A, B, C) = (a + A, b + B, c + C) (a,b,c) + (A,B,C) = (a + A,b + B,c + C) This works in any number of dimensions, not just three.
