What is the difference between vector and scalar quantities. give an example of both.​

The difference between vector and scalar quantity are:

i) Vectors have both magnitude and direction.

ii) The sum of vectors may be positive, zero or negative.

iii) Vectors are added by the rules of vector algebra.

iv) For example: velocity, acceleration,force , weight etc...

i) Scalars have only magnitude

ii) The sum of scalars is always positive.

iii) Scalars are added by the rules of simple algebra.

iv) For example: length,time ,volume ,area etc

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
