🔶05 - Scalar or Dot Product, Vector and Scalar projection of a Vector onto another
In todays video, we shall discuss
1. how to find the scalar or dot product of two vectors
2. properties of dot products
3. Scalar and Vector projection of a vector onto another
A Scalar is a quantity that is completely defined by a single value(magnitude) with an appropriate unit. Eg, mass, length, speed.
A vector is a quantity that is completely defined when we know not only its magnitude but also the direction in which it operates.
Eg. force, acceleration, velocity.
