Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
False. Momentum is a vector quantity because it has both magnitude and direction.
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
The units are KgMs- why? Velocity is a vector Quantity and mass is a scalar quantity.
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.
Power momentum is a scalar quantity, as it is a measure of the rate at which work is done or energy is transferred. It does not have a direction associated with it, unlike vector quantities such as velocity or force.
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
False. Momentum is a vector quantity because it has both magnitude and direction.
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.

In a vector quantity, it is important to specify a direction. In a scalar quantity, it isn't. Vectors (such as force) have a magnitude (size) and a direction (such as North). Scalars have only a magnitude.
Yes, 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, and the direction of momentum is the same as the direction of the object's velocity.
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.

temperature is a scalar quantity................
No, momentum conservation is a fundamental principle in physics and it would still hold even if momentum were not a vector quantity. Momentum conservation simply states that the total momentum in a system remains constant unless acted upon by an external force. Whether momentum is treated as a vector or scalar quantity does not change this principle.
