What is the dot product of two parallel vectors.
Work done by force → F: W = ∣∣ ∣→ F ∣∣ ∣ ⋅ ∣∣→ s ∣∣ ⋅ cos(θ) Where θ is the angle between force and displacement; the two vectors being parallel can give: θ = 0° and cos(θ) = cos(0°) = 1 so: W = 5 ⋅ 10 ⋅ 1 = 50J Or: θ = 180° and cos(θ) = cos(180°) = − 1 so: W = 5 ⋅ 10 ⋅ − 1 = − 50J Answer link
I've learned that in order to know "the angle" between two vectors, I need to use Dot Product. This gives me a value between $1$ and $-1$. $1$ means they're parallel to each other, facing same direction (aka the angle between them is $0^\circ$). $-1$ means they're parallel and facing opposite directions ($180^\circ$).A Dot Product Calculator is a tool that computes the dot product (also known as scalar product or inner product) of two vectors in Euclidean space.
