The kinetic energy store
In this lesson we will be exploring the kinetic energy store. We'll define what this is, how to calculate it for different objects and how to change the value of the kinetic store.
The gravitational potential store
In this lesson we're going to start exploring the topic of energy stores and transfers. We're specifically going to be looking at the gravitational potential energy store, and how to calculate values of this.
Conservation of energy
In this lesson we will be studying the law of conservation of energy with a focus on conservation of energy during transfers between the kinetic store and gravitational potential energy store.
The elastic potential store
In this lesson we will explore the elastic potential energy store. We will look at the factors that affect its value, and how to calculate this.
Power
In this lesson we will be looking at what defines the power of an object, and how to calculate power.
Efficiency and reducing unwanted energy transfers
In this lesson we will be exploring the topic of reducing energy losses. We will consider how this affects the efficiency of a system and use this in calculations.
Specific heat capacity
In this lesson we will be exploring the effects of adding energy to a system and its effect on temperature. We will look at how this leads to a definition of the property of specific heat capacity and how to calculate this for different materials.
Specific heat capacity required practical
In this lesson we will be applying our understanding of specific heat capacity to complete one of the required practicals for the physics part of the course. We will perform an investigation to determine specific heat capacity, and in the process consider effects on uncertainty in our readings.
Insulating material required practical (Part 1)
In this lesson we will look at developing a method to investigate the rate of cooling of water. We will focus on the key variables and actions required to be successful with this experiment.
Insulating material required practical (Part 2)
In this lesson we will analyse results from the insulating material required practical and look at how this then applies to exam question contexts.
Non-Renewable energy resources
In this lesson we will be exploring the topic of non-renewable energy resources and their impact on the environment.
Renewable energy resources
In this lesson we will be exploring the advantages and disadvantages of renewable energy resources. We will then compare their use with non-renewable resources.
Multi-Step calculations for the energy topic
In this lesson there will be a focus on the mathematical skills related to the higher tier aspects of the energy topic. We will explore approaches to solving complex, multi step calculations to describe the energy transfers taking place in different systems.
Energy review
This lesson will be a revision of the content covered in this topic. There will be a focus on recalling the knowledge from this topic and applying it to different types of questions.
Case study: Esther Takeuchi
In this lesson we will be exploring the work of Esther Takeuchi, a materials scientist and chemical engineer, working on energy storage systems and power sources for biomedical devices.
