Is momentum a scalar quality

Answer 1

A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator.

An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector.

The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.

Answer 2

No, momentum is a vector quantity because it has both magnitude and direction. It is defined as the product of an object's mass and its velocity, with the direction determined by the direction of the velocity.

Answer 3

Momentum is a measure of how hard it is to stop an object.

Answer 4

No, vector quantity. :)

Answer 5

momentum is vector quantity.

Answer 6

False
