How to calculate a dot product A dot product is the multiplication of two vectors to form a scalar. There are two ways to calculate the dot product. where θ is the angle between A and B Component of A along B A θ B

Examples of Dot Products

Definition of Work Work is defined as the amount of force acting over a distance. The unit of work is either Joules (J) or electron-volts (eV) Dr F

Example of Work y Δw Δh1 x m Δh2 The following is an example of the work done by gravity on a mass. y Δw Δh1 x m Δh2

Example of Work F (N) 1 -1 A1 X (m) 1 2 A2 This is an example using the the fact that integrals are areas under a curve. F (N) 1 -1 A1 X (m) 1 2 A2
