Scalars are quantities which are measured by their magnitude, while vectors have both magnitude and direction. Multiplying two scalars produces another scalar, but multiplying vectors is more complicated. In fact, there are two different ways to multiply two vectors: one produces a scalar, and the...
Examples of Scalar and Vector Quantities Lesson Summary Frequently Asked Questions What is another word for scalar? Another word for a scalar is magnitude. A scalar quantity gives an indication of how small or large a physical quantity is. What is scalar and vector? A scalar quantity is the...
Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Thus, a velocity of 50 km/h due east, on acceleration of 9.8 m/s 2 vertically downward, and a ...
A physical quantity is the measurable and quantifiable physical property that carries unique information with it. Based on the dependency of direction, physical quantities can be classified into two categories — scalar and vector. Let us now discuss wha
Work is a scalar quantity, even though it's calculated by using two vector quantities (force and displacement). A、正确 B、错误

Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Thus, a velocity of 50 km/h due east, on acceleration of 9.8 m/svertically downward, and a force...
How to Distinguish Between Vector and Scalar Quantities Step 1:Identify the units for the quantity and determine if the quantity described has a direction associated with it. Step 2:Identify the quantity as a vector or a scalar. Vector quantities involve a magnitude (number) with units and a ...
