What Should You Expect From This Lesson? Name physical quantities that you know: mass, time, speed, weight, energy, power, … Scientists can even make up a completely new physical quantity that has not been known if necessary. However, there is a set of limited number […]

What Should You Expect From This Lesson? Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. Power is defined as work done per unit time. The standard unit of work is […]

What Should You Expect From This Lesson? In this lesson you will learn that energy can take different forms and can be transferred from one form to another. You will find that energy is discussed in many everyday, as well as scientific, contexts, because it […]

What Should You Expect From This Lesson? Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance. The law is named after 17th century British physicist […]

What Should You Expect From This Lesson? This lesson deals with pressure in solids, liquids and gases. You will learn about the basic principles that hydraulic systems use to do their work. How To Carry Out This Lesson At Home: Pressure is defined as the […]

What Should You Expect From This Lesson? Turning forces are found in many everyday situations and are essential for machines to function. Levers and gears make use of these turning forces to provide an advantage. How To Carry Out This Lesson At Home: We define […]

What Should You Expect From This Lesson? A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. How […]

What Should You Expect From This Lesson? This lesson includes worksheets with accompanying answers on the solar system and how day and night are brought about on our planet. It is intended for track 1 students. How To Carry Out This Lesson At Home: The […]

What Should You Expect From This Lesson? Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object. For example, we feel heat from the sun even though we are not touching it. How […]

What Should You Expect From This Lesson? Convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts , becomes more dense and then sinks. Applications of convection currents in real life situations are discussed. How To […]

What Should You Expect From This Lesson? This lesson deals with the transfer of energy, such as heat or an electric charge, through a substance. In heat conduction, energy is transferred from molecule to molecule by direct contact; the molecules themselves do not necessarily change […]

What Should You Expect From This Lesson? The lesson deals with specific heat capacity as the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. How To […]

What Should You Expect From This Lesson? The lesson deals with the kinetic theory of matter. The three states of matter are discussed. The differences between evaporation and boiling are discussed. How To Carry Out This Lesson At Home: Read through the notes on state […]

What Should You Expect From This Lesson? This lesson covers the solar system, planets satellites stars, measuring distances in space and the benefits of space exploration. How To Carry Out This Lesson At Home: Read though through the material and fill in the blanks as […]
