Energy Transfer
This word means moving energy from one object or system to another
Transfer
Sound travels fastest through THIS type of material
Solids
Energy from the sun is called THIS type of energy
Radiant energy
In a toaster, electrical energy transforms into THIS
Thermal/Heat energy
THIS type of energy depends on an object's position or height
Gravitational energy
When you throw a ball, THIS type of energy is transferred
Kinetic energy
THIS determines the pitch of a sound
Frequency
Light energy travels in THESE
Waves
When a bow moves on a violin, mechanical energy transforms into THIS
Sound energy
Electrical energy is created by THESE
Chemical reactions
Explain the difference between energy transfer and energy transformation
Energy transfer moves energy between objects, while energy transformation changes energy from one form to another
Explain how a violin creates sound energy
Mechanical energy of the bow movement transforms into sound energy
Thermal energy is best described as the energy of WHAT?
Energy of heat and moving particles
Describe how a battery converts chemical energy
Converting stored chemical energy into electrical energy
Explain how amplitude affects the loudness of sound
Greater amplitude creates louder sounds
Describe how energy moves in a windmill from wind to electricity
Wind's kinetic energy spins turbine blades (mechanical energy), which turns a generator to create electrical energy
Describe how human ears convert sound waves into signals
Sound waves are mechanically transformed through ear structures into neural signals that the brain interprets
Explain the difference between chemical and nuclear energy
Sound waves are mechanically transformed through ear structures into neural signals that the brain interprets
Explain how a solar panel transforms solar energy
Solar panels convert light energy directly into electrical energy
Describe how different energy types can be converted
Energy can be converted through various processes like mechanical, electrical, or chemical interactions
Explain in detail how energy can transfer between multiple objects without losing its total amount
Energy can transfer between objects through various methods like heat, sound, or mechanical movement, but the total amount of energy remains constant
Provide a complex explanation of how sound wave frequency and amplitude interact to create different sound experiences
Sound frequency determines pitch (higher frequency = higher pitch), while amplitude determines loudness (greater amplitude = louder sound)
Describe the unique characteristics of nuclear energy and how it differs from other energy types
Analyze the most efficient ways energy can be transformed from one type to another with minimal energy loss
Most efficient transformations minimize energy loss through methods like using direct conversions and avoiding multiple intermediate energy changes
Explain the concept of conservation of energy and how energy cannot be created or destroyed, only changed from one form to another
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another
