2. Provide two examples of a scalar quantity, and two examples of a vector quantity: 3. Circle which measurements are scalar quantities: a. 12ms b. 3.2m[up] c. 15cm d. 500 MHz e. 100 km/h [west] f. 50 mL Average Speed (p.7) 4. Provide a word definition for average speed ...
This chapter discusses the quantities used in engineering and science, and can be divided into two groups. Scalar quantities have a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector ...

Scalar quantities involve a magnitude with units, but no direction. What is a Vector Quantity and a Scalar Quantity? Vector Quantity:A vector quantity is a quantity that has both a magnitude and a direction. Magnitude refers to a number with units, and the direction makes the quantity a vect...
Angle = tan-1 (opposite leg (y) / adjacent leg (x)) The Tangent Function The inverse tangent function can be used to find the direction of the resultant For any right triangle, the tangent of an angle is defined as the ratio of the opposite and adjacent legs Angle = tan-1 (opposite...
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
