uniform circular motion.

### Motion in a Plane

In this section, we shall see how to describe motion in two dimensions using vectors. Position Vector and Displacement: The position vector r of a particle...

### Scalar

A scalar quantity is a quantity with magnitude only. It is specified completely by a single number, along with the proper unit. Examples are: the...

### Resolution of a vector in a plane and Unit Vector

Resolution of a Vector in a Plane: Let a and b be any two nonzero vectors in a plane with different directions and let A...

### Vectors

In physics, we can classify quantities as scalars or vectors. Basically, the difference is that a direction is associated with a vector but not...
