scalar product
inner product
dot product

The scalar product of a four-velocity and the corresponding four-acceleration is always 0.

This formula does not explicitly depend on the definition of the scalar product.

The prototypical example of a pseudoscalar is the scalar triple product.

The scalar product of the differential 4-position with itself is:

This scalar product of force and velocity is classified as instantaneous power.

The scalar products met in vector analysis are familiar examples of contraction.

(see above), the scalar product of d and m must be zero!

Another simple way to look at it as a scalar product of vectors in module 10.

The scalar triple product is invariant under rotation of the coordinate system.

This definition therefore depends on the definition of the scalar product.
