PHYSICS ACTIVITY ON STEEMIT PHYSICS CLASS LESSON 2- CLASSIFICATION OF QUANTITIES AND UNITS BY @FAVOUR11

Hello @whileponderin I really learnt Alot from you lesson today. It is so self explanatory. Though I always look at physics to be hard. I understand everything I decided to do the activity . HERE ARE MY ANSWERS

1

Difference between fundamental quantity and derived quantity

Fundamentals quantity

• They are the basic quantities
• They are independent
• They are only seven
• Eg mass, length

Derived quantities

• They are the derived quantity
• They depends on other quantities
• Eg velocity, volume
• They are large in numbers

2

List three examples of fundamental quantities and the unit

• Quantities
  Length
  Mass
  Time
• Unit
  Metre
  Kilograms
  Second

3

List three examples of derived quantities and the unit

• Area | m^2
  Pressure | Pa
  Density | kg m^3

4

What is the difference between scalar and vector quantity

Vector

• It has magnitude with a particular direction
• It can be two or more dimensions
• Eg are mass, length
  Scalar
• It has magnitude with no direction
• It has one dimensions
• Eg are velocity, polarization

Conclusion
Thanks for the lesson. Please check my activity. Thanks take care and stay safe.
