This is a 12 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Efficiency and Mechanical Advantage as applied to lifting machines in engineering. This is the seventh PowerPoint in this section which covers Mechanical Advantage and Velocity Ratio in ideal systems and then applies this to non-perfect scenarios so that efficiency can be calculated. The lifting machine of a block being pushed up a slope is used throughout this PowerPoint to cover this topic in an easy to understand manner. This is extended to more complex listing machines in the next PowerPoint in the series.

This is a 6 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Capacitors in both series and parallel circuits. This PowerPoint includes circuit diagrams and worked examples of the capacitance, current and voltage calculations needed for basic circuits. This is an extension from the earlier lesson where capacitance and capacitors were introduced in detail. This is the sixth PowerPoint in this section (Electricity and circuits).

This is a 9 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Simply Supported Beams which is supported with a worksheet with three questions including answers. This covers the mathematical and physics for a Beam system including point forces, Uniformly Distributed Forces (UDL) on a beam with pins and rollers. There is a brief recap of the principle of moments and an animated worked example of a beam question. This PowerPoint forms Lesson 3 in this series

This PowerPoint lesson on Orbits and Orbital Motion covers the mathematics of circular motion (at iGCSE physics level) and applies this to the orbits of the planets, moons and satellites. Various types of satellite orbits are also considered including geostationary orbits. This is the second (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop

This is a lesson and PowerPoint that covers exoplanets, including an analysis of both the transiting and radial velocity methods and a comparison of their individual merits. As well as supporting A-Level Physics for many exam boards this lesson is also part of a chapter that covers the optional astrophysics unit 9 for AQA Please see my shop to view all of my lessons and entire schemes of work

This is a lesson and PowerPoint that covers supernova (Type II and Ia), light curves and hydrogen lines of supernova, black holes (Schwarzschild radius calculations and Chandrasekhar limit), gamma ray bursts and the overall luminosity of these events. As well as supporting A-Level Physics for many exam boards this lesson is also part of a chapter that covers the optional astrophysics unit 9 for AQA

This is a lesson and PowerPoint that covers luminosity of stars, Wein’s displacement law, black body radiation, stellar classification, stellar spectral analysis and flux density calculations. As well as supporting A-Level Physics for many exam boards this lesson is also part of a chapter that covers the optional astrophysics unit 9 for AQA Please see my shop to view all of my lessons and entire schemes of work

iGCSE - Refraction of light and refractive index This lesson covers the refraction of light and the calculation of refractive index when passing from air into transparent materials. This lesson also demonstrates the experiment that can be performed, step-by-step with animation. There are also two examples of light entering and exiting other shapes (prism and edge of a square) which can cause pupils issues in exams.

iGCSE - Total Internal Reflection This lesson covers the refraction of light and the calculation of refractive index as applied to the phenomenon of total internal reflection. This lesson also demonstrates the experiment that can be performed, step-by-step with animation.

This is a 7 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Tensile and Compressive forces which create stress and strain. This then goes on to explain how this relates to the Modulus of Elasticity (Young Modulus). Three question sheets are included complete with worked answers. This is the first of three PowerPoints in this series and covers the mathematical and physics for an analysis of Stress and Strain in Engineering materials v1.1 - PDF question sheets and worked answers added to resource v1.11 - Two more sets of questions and answers added to resource; minor improvements to ppt also made v1.12 - Error on the answer sheet corrected v1.13 - Jan 2023 Error on Powerpoint corrected

This is a lesson that explains basic differentiation leading onto a proof of Euler's number and the use of this in creating exponential decay formulae. This PowerPoint is designed to take you step by step through the derivation of the formulae used in Physics for the decay of isotopes or other exponential experiments.

This is a 15 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Lifting Machines which includes The Inclined Plane, Pulleys, Screw Jacks and Scissor Mechanisms. This is the eighth and final PowerPoint in this section which covers each of these main lifting mechanisms and includes worked example calculations for each example.

This is an 8 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of B-H curves. This PowerPoint includes a description of how to plot a graph of B (magnetic flux density in a material) against H (magnetic field from a solenoid) and then goes into detail about analysing the graph to consider coercivity and hysteresis based on permeability. This is the second PowerPoint in this section (Magnetism and Electromagnetic induction).

This is a 9 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topics of Diodes in circuits. This lesson covers the three main rectification circuits, complete with animated diagrams to help students understand how they create the DC output from an AC input for bi-wave and full-wave variants. Protection circuits and the use of Zener diodes are also briefly covered, together with an worked example circuit question. This is the fourth PowerPoint in this section (Electricity and circuits).

This PowerPoint lesson on Stellar Evolution covers the development of a star through its entire life. This powerpoint includes the iGCSE details linking surface temperature to the colour of star and the ultimate ending paths of stars depending on their mass. A poster / flow chart activity idea is also included. This is the third (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop.
