Question

briefly explain the types of physical quantities ​

Answer 1

Explanation:

physical quantities are classified into two types. there are fundamental and derived quantities. fundamental or base quantities are quantities which cannot be expressed in terms of any other physical quantities. these are length, mass, time, electric, current, temperature, luminous intensity and amount of substance. quantities that can be expressed in terms of fundamental quantities are called derived quantities for example: Area, volume, velocity, acceleration, force

Answer 2

Answer:

• Physical quantities is a quantity in physics that can be measured.
• Thus physical porperties would be measured.
• There 7 main physical properties .
• The example of physical properties are as follow :

1. Length :The one dimensional extent of object, denoted by (l)
2. Current: Rate of flow electric charge per unit time ,denoted by (l)
3. Mass: A measure of resistance to acceleration (m)
4. Time:Duration of event ,denoted by(t)
5. Temperature: Average kinetic energy per degree of freedom of system,denoted by (T)
6. Luminous intensity :Wave length weighted power of emitted light per unit solid angle ,denoted by (lv)
7. Amount of substance :Avogado constant as proportionality constant,denoted by (n) .
