Introduction to Vectors and Scalars



Introduction to Vectors and Scalars
A vector is a quantity that has both length and direction, while scalars
only have length. Examples of scalars include acceleration, electric
field, and electric charge. Scalar multiplication of vectors follows
distributive property.

Vector Addition and Subtraction
Vector addition involves drawing two vectors in the same plane and
adding them head to tail. Vector subtraction is simply adding the
opposite vector, which points in the opposite direction. Jeff
demonstrates how to add and subtract vectors from head to tail and
explains the usual rules of algebra that vectors follow.

Vector Calculus and Theory
Vector calculus is a branch of mathematics that deals with vectors
and their properties. It is used in the theory of gravity and its
dynamics. The theory of vector calculus is the theory of vector
arithmetic and its analysis. The definition of gravity is a simple one,
and it uses the theory of vectors to calculate it.

Conclusion
Jeff shows how vectors are objects that have both length and
direction and follow the usual rules of algebra. He also demonstrates
how to draw vectors from tail to tail and add and subtract them. The
theory of vector calculus is used in the theory of gravity, and it is a
simple definition that uses the theory of vectors to calculate it.
