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.
Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
Why velocity may be zero but speed cannot be zero?
Velocity is a vector quantity that includes both magnitude (speed) and direction. Thus, velocity can be zero if there is no motion, but speed is the magnitude of velocity and cannot be negative. Speed is always a positive scalar quantity, so it cannot be zero if there is any motion at all.
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
Can a scalar product by a negative quantity?
Yes, a scalar product can be negative if the angle between the two vectors is greater than 90 degrees. In this case, the dot product of the two vectors will be negative.
What is a scalar which is both positive and negative?
Scalar is a type of quantity which contains magnitude only and has no direction. For example: distance and speed

Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
Can a scalar quantity have a zero magnitude?
All scalar quantities have magnitudes; what scalars don't have is direction. The magnitudes can take any value, +ve or -ve (or zero).
Can you add zero to a null vector?
scalar cannot be added to a vector quantity
Why velocity may be zero but speed cannot be zero?
Velocity is a vector quantity that includes both magnitude (speed) and direction. Thus, velocity can be zero if there is no motion, but speed is the magnitude of velocity and cannot be negative. Speed is always a positive scalar quantity, so it cannot be zero if there is any motion at all.
How do you find the volume of a sphere if the radius is a negative number?
radius is a scalar quantity, it can not have a negative value.
How will you show that the isplacment of a body can be zero but the distancecan never be zero?
Displacement is a vector quantity which refers to the distance moved with respect to a position. If the position is home, once you are home, displacement is zero. Distance is a scalar quantity which refers to the distance moved. This can be counted from the start to end. Since scalar quantity cannot go negative (it cannot drop but only rise), it can never be zero. If you moved 1 metre north then 1 metre south, displacement is zero metre but distance is 2 metre.
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
Why work is negative its is scalar quantity?
A scalar quantity may have positive and negative values - it is simply a real number. But it doesn't have a direction. Think of it as a "vector in one dimension" - whereas the usual vectors have at least 2 dimensions.
Is temperature a scalar quantity or vector quantity?
temperature is a scalar quantity................
Is current a scalar or vector quantity?
It depends upon the condition.But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.
