Study Notes

Energy Overview

Energy is the capacity to perform work.
Essential for machinery and various processes.

Measurement of Energy

Joule is the standard unit for measuring energy.
Symbol for joule is J.

Forms of Energy

Elastic potential energy: Stored in stretched or compressed materials.
Chemical potential energy: Found in fuels, batteries, and food.
Gravitational potential energy: Associated with objects raised above ground level.
Kinetic energy: Related to moving objects; absent in stationary objects.
Electrical energy: Present in circuits when current flows; can be converted to other energy forms.
Light energy: Necessary for visibility and photosynthesis in plants.
Sound energy: Allows for hearing and communication.
Thermal energy: Provides warmth and facilitates cooking.

Potential Energy

Potential energy refers to energy that is stored and not in use.

Specific Forms of Potential Energy

Elastic potential energy: Found in materials that can be stretched or compressed.
Chemical potential energy: Stored in chemical bonds within substances.
Gravitational potential energy: Depends on an object's height relative to the ground.

Temperature and Heat Transfer

Temperature measures how hot or cold an object is.
Measured using a thermometer or temperature sensor.
Thermal energy transfers from hot to cold areas.

Principles of Energy Conversion

Energy is neither created nor destroyed, only transformed.
Energy can shift from one form to another, keeping total energy constant before and after conversion.

Understanding Power

Power measures the rate of energy conversion or transfer per second.
Increased power results from converting or transferring more energy in the same timeframe.
