Page 2: Power and Energy Transfer

This page focuses on power calculations and energy transfer concepts, particularly in the context of electrical devices like light bulbs.

Definition: Power is defined as the rate of energy transfer, calculated using P = W/t (work done divided by time)

Example: In a light bulb, electrical energy is transferred to light and heat, with some energy being dissipated as waste

Vocabulary: Specific heat capacity is the amount of energy required to raise the temperature of 1kg of a substance by 1°C

Highlight: The formula ΔE = mcΔθ is used to calculate thermal energy changes, where m is mass, c is specific heat capacity, and Δθ is temperature change

Page 3: Efficiency and Renewable Energy

This page examines efficiency calculations and various renewable energy sources, along with electrical circuit components.

Definition: Efficiency is calculated as the ratio of useful energy output to total energy input, expressed as a decimal or percentage

Example: Renewable energy sources include solar, wind, hydroelectric, and geothermal power

Highlight: The page distinguishes between renewable resources (infinite, sustainable) and finite resources (fossil fuels, nuclear)

Vocabulary: Circuit components covered include voltmeters, ammeters, diodes, resistors, and LEDs

Page 1: Energy Types and Calculations

This page introduces fundamental energy types and their mathematical formulas. The various forms of energy covered include kinetic, potential, elastic, chemical, nuclear, light, sound, and thermal energy.

Definition: Kinetic energy is the energy possessed by an object due to its motion, calculated using Ek = ½mv²

Vocabulary: Gravitational potential energy (Ep) represents the energy stored in an object due to its position in a gravitational field

Example: A spring's elastic potential energy can be calculated using the formula Ee = ½kx², where k is the spring constant and x is the extension

Highlight: The page presents three key energy equations: kinetic energy (Ek = ½mv²), gravitational potential energy (Ep = mgh), and elastic potential energy (Ee = ½kx²)

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.
