(1) The car is going 75 mph. This is a scalar value because you don’t know which direction the car is going. (2) You walked 4 mph toward the store. This is a vector because you have both a magnitude and a direction. (3) The box in the west corner of the room has a mass of 12 kilograms. The mass of the box is a scalar quantity. Even though you know ...
A unit vector is a vector that has a magnitude of 1. Usually, it’s indicated by placing a carat (^) over it. The unit vector x, with a carat over it, is read as “x-hat” because the vector looks som...The null vector or zero vectoris a vector with a magnitude of zero. While it has no magnitude, it has a direction. For example, you could use a null vector to describe which direction a compass is...Ashcroft, Neil; Mermin, N. David (1976). Solid State Physics.

ISBN 0-03-010567-6.The weight of an object acts in the downward direction. If a scalar is multiplied by a vector, the magnitude and direction of the resultant quantity may change, but the resultant quantity is always a vector, according to the law of vectors or algebra of vector.
Aug 25, 2020 · Weight varies according to location. Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and direction. The direction is toward the center of the Earth or other gravity well. Mass may be measured using an ordinary balance. Weight is measured using a spring balance. Mass is measured in grams (g) and ...
Some standard textbooks [4] define weight as a vector quantity, the gravitational force acting on the object. Others [5][6] define weight as a scalar quantity, the magnitude of the gravitational force.
Since weight has both a magnitude and a direction, weight is a vector quantity. We saw earlier that distance is a scalar quantity—it is fully defined by a magnitude. When thinking about distance, we used an example with walkers who each walked different routes starting from the same position.
Jan 12, 2024 · A physical quantity that can be specified completely in this manner is called a scalar quantity. Scalar is a synonym of “number.” Time, mass, distance, length, volume, temperature, and energy are examples of scalar quantities.
