Specific gravity is a scalar quantity. It is defined as the ratio of the density of a substance to the density of a reference substance, typically water. Since it does not have a direction associated with it, it is classified as a scalar rather than a vector.
Gravity is a force, and forces have magnitude and direction; hence, it is a vector.
Since you can represent that with a single number, it isn't a vector - just a scalar.
A scalar times a vector is a vector.
vector
Gravity is a vector, because it is a form of acceleration (which we know by definition is a vector). Vectors hold more 'information' than scalars, because vectors are, put simply, a scalar + a direction. To help you figure out these types of questions in the future, all you have to do is figure out whether direction is an important aspect of the value in question.
WEIGHT is a VECTOR quantity .. because the weight has the direction into the surface of the earth to the down effected by the gravity .. but mass is a scalar quantity like 90 kg .. so .. WEIGHT IS VECTOR ..
It's a 0th order tensor, also known as a scalar.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
No, upthrust is not a scalar quantity. It is a vector quantity as it has both magnitude and direction. Upthrust is the upward force exerted by a fluid on an object immersed in it, and its direction is always opposite to the direction of gravity.
Average speed is a scalar quantity because it only has magnitude and does not have a specific direction associated with it.
No, upthrust is not a vector. It is a force that acts in the opposite direction to the force of gravity on an object. It is a scalar quantity and only has a magnitude, not a direction.
