Two type of numbers - Vector and scalar.

Vectors And Scalars

Define vector and scalar quantity

Properties of Multiplication of a vector by a scalar

Is it possible that the sum of two vectors is a scalar ?

Explain multiplication of a vector by (i) a real number (ii) by a scalar.

Is potential energy a vector or scalar quantity ?

Multiplication Of A Vector By Scalar

State with reasons whether the following algebric operations with scalar and vector phisical quantities are meaningful : (a) adding any two scalars (b) adding a scalar to a vector of the same dimensions (c) multiplying any vector by any scalar (d) multiplaying any two scalars (e) adding any two vectors (f) adding a component of a vector to the same vector .

If two non-zero vectors are perpendicular to each other then their Scalar product is equal to ?

Assertion: The dot product of one vector with another vector may be scalar or a vector. Reason: If the product of two vectors is a vector quantity, then product is called a dot product.
