Multimedia-rich lesson resources. Original videos, crystal-clear content and worksheet. GCSE Physics: Gravitational Potential Energy. Fourth in a series of 11 lessons covering the unit: “Conservation and Dissipation of Energy” Lesson 4: Gravitational Potential Energy Clear learning objectives: Gravitational potential energy (GPE) is increased by lifting an object against the effects of gravity. We can use an equation to calculate gravitational potential energy. Work done on an object against gravity causes the object to store GPE. Use as a stand-alone lesson or part of a sequence Full set of lesson resources PowerPoint presentation with embedded videos A quick and engaging starter to display on the board Original MM Science videos to supplement content Modelled calculations Real-life examples Worksheet activity and answers incorporated into lesson resources Additional videos to reinforce understanding of learning objectives Mini whiteboard multichoice questions as a quick test of learning A True or False discussion to get at the heart of some common misconceptions MM Science are Martin and Mike, two Science teachers with specialisms in Physics and Biology and having nearly 60 years of teaching experience in state comprehensive and grammar schools.

Multimedia-rich lesson resources. Original videos, crystal-clear content and worksheet. GCSE Physics: Energy Dissipation. Seventh in a series of 11 lessons covering the unit: “Conservation and Dissipation of Energy” Lesson 7: Energy Dissipation Clear learning objectives: Energy is transferred into useful energy when it is in a form that we need, in the place that we need it Energy is transferred into wasted energy when it’s not the form we want, in the place we want it Friction causes kinetic energy to be transferred to thermal energy Energy eventually transfers into the surroundings causing them to become a tiny bit warmer Energy spreads out, or dissipates, getting less useful Use as a stand-alone lesson or part of a sequence Full set of lesson resources PowerPoint presentation with embedded videos A quick and engaging starter to display on the board Original MM Science videos to supplement content Modelled calculations Real-life examples Differentiated worksheet activities and answers incorporated into lesson resources Additional videos to reinforce understanding of learning objectives Mini whiteboard multichoice questions as a quick test of learning MM Science are Martin and Mike, two Science teachers with specialisms in Physics and Biology and having nearly 60 years of teaching experience in state comprehensive and grammar schools.
