  Form 3: Measurement and Physical Quantities Good day, students! My name is SirKhulu and I will be walking you through the Topics that yo are expected to have covered by the end of your Form 3 and 4 in Physics. Today, we will delve into the fascinating world of physics, specifically focusing on Measurement and Physical Quantities. Let's begin with the fundamental concepts that you need to grasp. 1. Measurement of Physical Quantities: In physics, measurement is a crucial aspect. We use measurements to quantify various physical properties. The basic quantities we measure include length, mass, time, electric current, temperature, amount of substance, and luminous intensity. These are known as fundamental quantities. Example: Consider measuring the length of this room. We use a ruler or a measuring tape and express the length in meters (m). 2. Derived Quantities: Derived quantities are combinations of fundamental quantities. They do not have separate dimensions but are derived from th...
