Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
Is mass classified as a vector quantity or a scalar quantity?
Mass is a scalar quantity, because it is a constant value no matter where you are, no matter what direction you are heading. Your mass on Earth will be equal to than on Jupitor or in space in general, the weight is the one that changes. (vector)
Is mass a scalar quantity?
Mass is a scalar quantity. Scalar quantities are those characteristics of matter that can be measured with a scale, while vector quantities are those that involve direction as well as quantity.
Is radius a scalar?
Yes. A scalar is a physical quantity that does not depend on direction. For example, temperature is a scalar because it has no directional value. Velocity is not a scalar (it is a vector quantity) because it has direction.
Will the value of vector quantity change if reference axis are changed?
no.
Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
What two quantities are necessary for a vector quantity?
a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
Is mass classified as a vector quantity or a scalar quantity?
Mass is a scalar quantity, because it is a constant value no matter where you are, no matter what direction you are heading. Your mass on Earth will be equal to than on Jupitor or in space in general, the weight is the one that changes. (vector)
Is the value of a scalar quantity dependent on the reference frame chosen?
Yes it is.
If the equation E equals mc squared gives energy which is a scalar physical quantity how is this possible when multiplying a scalar and a vector results in a vector quantity?
Energy is a product of 1 scalar quantity which is mass and 1 vector quantity which is the velocity of light within a vacuum. The velocity of light in the equation is squared which returns an absolute value negating any sign it has. This results in both terms having no sign. A vector quantity must have both a direction and a magnitude. The product returned will always be a positive quantity which means it has no direction.
Why is the fundamental value of a quantity not changed when the quantity is multiplied by a conversion factor?
the conversion factor merely changes the number in such a way that it fits the new units the physical quantity is not changed
Is momentum a vector?
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.
Is volt a vector quantity?
no volt is not a vector quantity because it has no direction and it can be added or subtracted as scalar quantities. volt in electrostatics is analogous to vertical height in mechanics . vertical height have a value for every place but no direction and height can be added or subtracted as scalar
Is mass a scalar quantity?
Mass is a scalar quantity. Scalar quantities are those characteristics of matter that can be measured with a scale, while vector quantities are those that involve direction as well as quantity.
