What does the Principle of Conservation of Energy state?
Energy cannot be created or destroyed
In a closed system, what happens to the total amount of energy?
The total amount of energy stays the same
What are some common forms of energy?
Kinetic Energy: Energy of motion
Potential Energy: Energy stored due to position or state
Thermal Energy: Energy from heat
Light Energy: Energy in the form of light
Sound Energy: Energy from sound waves
What is Thermal Energy?
Energy from heat
How can the concept of energy conservation be illustrated?
Energy is like a Lego set
Different models can be built (energy forms)
Total number of bricks (energy) stays constant
What is Potential Energy?
Energy stored due to position or state
What happens to kinetic energy when you kick a football?
Kinetic energy transfers to the ball
What is Sound Energy?
Energy from sound waves
How is heat transferred through radiation?
Through electromagnetic waves without a medium
What does it mean that total energy in a closed system remains constant?
Energy is conserved despite transformations
What is Kinetic Energy?
Energy of motion
What does "Dissipation of Energy" refer to?
Conversion of energy to a less useful form
What is nuclear energy?
Energy stored within atoms
What are the three main ways energy is transferred?
Conduction, convection, and radiation
What type of energy might be transformed due to friction when kicking a football?
Some kinetic energy transforms into thermal energy
What is chemical energy?
Energy stored in chemical bonds
How do different forms of energy interact?
Energy can transform from one form to another
Energy is always conserved during transformations
What occurs when a ball is released from a height?
Potential energy transforms back into kinetic energy
What happens to kinetic energy when a ball is lifted?
Kinetic energy converts to stored potential energy
What does it mean that energy is transferred from one form to another?
Energy changes forms but total amount remains constant
What are the methods of energy transfer and their descriptions?
Conduction: Heat transfer through solids
Convection: Heat transfer through fluids
Radiation: Heat transfer through electromagnetic waves
What is Light Energy?
Energy in the form of light
How is heat transferred through conduction?
By hot particles colliding with cooler ones
How does the total energy in a system change when energy transforms?
The total energy remains the same
How does energy dissipation relate to energy conservation?
Energy changes form but is not lost
How does photosynthesis illustrate energy conservation?
Light energy becomes chemical energy in glucose
What does the table illustrate about energy?
Creation and destruction of energy are not possible
How is heat transferred through convection?
As hot particles rise and cool particles sink
What is electrical energy?
Energy from moving electrons
What are the common methods of energy dissipation?
Friction: Energy lost due to rubbing surfaces
