In this lesson, we are going to discuss Archimedes’ Principle, where we will discuss what is upthrust? Why objects float in liquid? The relationship between upthrust and density, and what is stated in Archimedes’ Principle. After that we will discuss the equation of Archimedes Principle. Under the equation, we will learn how to find the … Read more
In previous lesson, we have discussed measuring gas pressure. In this lesson, we are going to discuss Pascal’s Principle, including its formula and applications. In SPM, there are a few thing s that we need to know about the Pascal’s Principle. First of all, of course we need to know what is stated in Pascal’s … Read more
In previous lesson, we have discussed atmospheric pressure, including the proofs of existence, measurement of atmospheric pressure and applications of atmospheric pressure. In this lesson, we are going to continue with measurement of gas pressure by using Bourdon Gauge and manometer. In SPM, most questions about measurement of gas pressure are related to manometer. Therefore, … Read more
In previous lesson, we have discussed liquid pressure, where we discussed the formula of liquid pressure, characteristics of liquid pressure and some applications of liquid pressure. In gas pressure, we are going to explain how gas pressure is produced by using the kinetic theory of gas. After that, we will shift to atmospheric pressure where … Read more
Force and Pressure is the 3rd chapter in SPM form 4 Physics. There are 6 main sub-topics in this chapter, namely pressure, liquid pressure, gas pressure, Pascal’s Principle, Archimedes Principle and Bernoulli’s Principle. In pressure, we will discuss what pressure is, the formula of pressure and applications of high and low pressure. In liquid pressure, … Read more
The second thing that you need to know about the F – x graph is how the spring constant can be determined from the graph. Spring constant is the ratio of force exerted on a spring to the extension or compression of the spring. Therefore, it is equal to the gradient of the graph. Let’s … Read more
In previous lesson, we have discussed energy, including the kinetic energy, the potential energy, the principle of conservation of energy and the work energy model. In this lesson, we are going to discuss power, equation of power, efficiency and equation of efficiency. In SPM, there are 3 points that you need to know about power: … Read more
In previous lesson, we have discussed work. In this lesson, we are going to continue with energy. First of all, we will discuss the definition of energy. After that we will discuss 2 types of energy: the kinetic energy and potential energy. There are 2 types of potential energy: gravitational potential energy and elastic potential … Read more
Force as a vector is the last part in this course. In SPM, under force as a vector, we need to learn addition of vectors, resolution of vectors, inclined plane and equilibrium of forces. In this lesson, we will focus on addition of forces, where we will discuss how to use the triangle law and … Read more
