Dot Product

The dot product is an essential concept in mathematics and physics.

In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.

The dot product of any two vectors is the product of the magnitude of the vectors and the cosine of the angle between them.

Consider an object being pulled by a vehicle along the ground by a rope. If the rope makes an angle theta with the horizontal axis, then the work done can be calculated using the dot product of the force applied to d...
