WORK When a force →F causes an object to move some distance →d, the work done is Work = →F ⋅ →d Example 8.5.6 A cart is pulled 20 feet by applying a force of 30 pounds on a rope held at a 30 degree angle. How much work is done? Solution WebDefining the Cross Product. The dot product represents the similarity between vectors as a single number: For example, we can say that North and East are 0% similar since ( 0, 1) ⋅ ( 1, 0) = 0. Or that North and Northeast are 70% similar ( cos ( 45) = .707, remember that trig functions are percentages .) The similarity shows the amount of one ...

WebAlgebraically speaking, the dot product refers to the sum of the products of the components of vectors. Therefore, if you have a vector with 3 components, your dot product formula would be: a•b = a₁ * b₁ + a₂ * b₂ + a₃ * b₃ In any space which have more than 3 dimensions, add more terms to your summation.
