Fundamental and Derived Quantities
This lesson covers the definitions of fundamental and derived quantities in physics. It explains how fundamental quantities serve as the base for deriving other quantities and the importance of measurement in physical science.
- 03:09 “And to the second one, which is the life quantity, it means there are subsets of the derived quantity, and every other thing from this can be, can be, is elementary to this meaning, it can be derived from the fundamental...”
- 00:00 “Hello, my name is Tijani Musa Alad-Bukho, I'm your Physiist teacher. The topic before us today is fundamental and derived quantities. At the end of the lesson, students should be able to differentiate between fundamental...”
- 25:24 “So the last one is in terms of units, the unit of mass is kilogram and that of weight is newton. Evaluation, divine, fundamental and the life quantity in your own language to the best of your knowledge. So explaining tha...”
Rational and Non-Rational Numbers
This lesson covers the identification of rational and non-rational numbers. It explains the characteristics of different number sets, including natural numbers, whole numbers, and integers. The lesson also discusses the significance of the number PI in relation to circles.
- 00:56 “And to determine particle appropriate values for the PI, the PI. Now, the PI is usually used doing what? A cycle, that's the cycle phase of the cycle, to bring in your PI. How do we determine that? Now, move on straight...”
- 19:01 “Now, with these two examples, we will give you an idea to what pi equation or pi really means. Now, you have some questions, which I expect you to do. You have said calculate 16 divided by 9 in 3 decimal places. 16 divid...”
- 15:03 “So I put it. So simply, move it. I have my pie is what my circumference is given. The circumference is given in 62.832 over what's my radios? My radios is 10. That is 10. Now, I have 2 radios makes 1 diameter. That's tim...”
Distance and Displacement
This lesson explains the concepts of distance and displacement in translational motion. It covers how to measure distance without considering direction and how displacement includes both distance and direction. The lesson also discusses the position of an object in relation to a reference point.
- 04:00 “be measured and calculated. However, on the other hand, when we consider the distance and the direction of an object, then we make reference to displacements and is a major difference, a major distinction between distanc...”
- 08:06 “the distance. If we look at the two of them, they are one of the major key measuring fundamental quantity. And that is the displacement is actually measured in meter written as this. And the distance as well, the unit, t...”
- 10:27 “And as such, there are so many things that can be measured about the length of an object. We might be interested in the thickness, we might be interested in the depth sometimes or the height. So measuring the distance of...”
