Page 2: Work Done and Specific Heat Capacity

This page covers the relationship between work done and energy transfer, along with detailed explanations of specific heat capacity. Work is done when a force causes object displacement, and this work equals energy transferred between forms.

Example: A 2kg mass of water requires twice as much energy to increase its temperature compared to 1kg of water due to having twice the number of particles.

Definition: Specific heat capacity is the amount of energy required to raise the temperature of a substance, calculated using ΔE = m × c × ΔΘ.

Highlight: Work done against friction causes temperature increases in objects due to energy transfer.

Page 3: Electrical Energy and Efficiency

This page details electrical energy calculations and efficiency concepts. It covers power formulas and their applications in electrical systems, along with efficiency calculations and insulation effectiveness.

Definition: Efficiency is calculated as (Useful Energy Output ÷ Total Energy Input) × 100.

Highlight: U-values measure insulation effectiveness - lower values indicate better heat insulation.

Example: A solid brick wall has a U-value of 2.0 W/m², while a cavity wall has 1.6 W/m².

Page 4: Kinetic and Elastic Potential Energy

This page explores kinetic energy and elastic potential energy calculations. It includes detailed formulas and their applications in real-world scenarios.

Definition: Kinetic energy is movement energy affected by mass and velocity, calculated using Ek = ½ × m × v².

Vocabulary: Spring constant (k) - indicates the stiffness of an object, with higher values meaning stiffer objects.

Highlight: When air resistance is negligible, all gravitational potential energy converts to kinetic energy (Ep = Ek).

Page 1: Forms of Energy and GPE

This page introduces fundamental energy concepts and gravitational potential energy. The conservation of energy principle states that energy cannot be created or destroyed, only transformed from one form to another. Various energy forms are explored, including kinetic, potential, electrical, and nuclear energy.

Definition: Gravitational potential energy (GPE) is stored energy due to a change in height, calculated using the formula Ep = m × g × h.

Vocabulary: Joules (J) - the standard unit of energy measurement, equivalent to Newton-metres (N/m).

Highlight: The gravitational field strength (g) is 9.81 N/kg unless otherwise specified in exam questions.
