Draw the vector ◦ Dissecting a Vector: Initial point, Terminal Point, Length/Magnitude, and ◦ Direction Initial point: the point where the vector starts ◦ Terminal point: the tip (or tail) of the vector ◦ Length/Magnitude: how long the vector is; the scalar ◦ quantity attached...
This is the opposite of a scalar, which is a quantity that only has magnitude and no direction. Speed is a scalar: for example, 60 miles per hour. Velocity is a vector: 60 miles per hour north. Distance is a scalar: four miles total. Read What is a Vector? | Vector Magnitude, ...
Quantity refers to the amount or number of something, while a unit is a standard measure used to express that quantity.
Why is displacement a vector quantity? What two quantities are necessary for a vector quantity? How do you determine the force on an object if there are multiple forces acting on it? In unit-vector notation, what is the sum of A = (5.4m)i + (1.4m)j and B = (-14.0m)i + (6.4...
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature arevelocity, momentum, force,electromagnetic fieldsand weight. A quantity or phenomen...
