Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Velocity.
Key Points
- The definition of a vector quantity is a physical quantity that has both magnitude and direction.
- The fact that velocity has both magnitude and direction makes it a vector quantity.
- The concept of velocity is used to describe the speed and direction of a moving object.
- A scalar quantity, such as time or length, may be fully described by a single number but a vector quantity, such as velocity, which has both direction and magnitude, cannot.
Additional Information
- Mass
- A scalar quantity is a mass.
- It is substantial.
- Common units of mass measurement are kilograms and grams.
- Temperature
- One example of a scalar physical quantity is temperature.
- It has a magnitude but no directional sense.
- Pressure, energy, concentration, and density are more instances of scalar quantities.
- Volume
- The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units.
- A derived measure called the cubic meter (m3) serves as the SI unit of volume.
- Volume is how much space an object occupies, whereas capacity is how much it can hold of a substance, such as a solid, liquid, or gas.
- Volume is expressed in cubic units, although capacity can be expressed in nearly any other unit, such as liters, gallons, pounds, etc.
