Solved Using The Scalar Product Of Two Vectors Determine Chegg Taking a scalar product of two vectors results in a number (a scalar), as its name indicates. scalar products are used to define work and energy relations. for example, the work that a force (a vector) performs on an object while causing its displacement (a vector) is defined as a scalar product of the force vector with the displacement vector. We can use equation 2.6.12 for the scalar product in terms of scalar components of vectors to find the angle between two vectors. when we divide equation 2.6.1 by ab, we obtain the equation for cos φ, into which we substitute equation 2.6.12: cosφ = →a ⋅ →b ab = axbx ayby azbz ab. 2.3.1 calculate the dot product of two given vectors. 2.3.2 determine whether two given vectors are perpendicular. 2.3.3 find the direction cosines of a given vector. 2.3.4 explain what is meant by the vector projection of one vector onto another vector, and describe how to compute it. 2.3.5 calculate the work done by a given force. Here’s the best way to solve it. solution the scalar product (dot product) of two vectors $\hat{i}$ and $\hat{i}$ is given by: $$ \hat{i} \cdot \hat{i} = 1 $$.
