Energy Flashcards
Describe what energy means in science
The definition of energy in science means the ability or capacity to do work
What are the Active Forms of Energy
Light Energy Sound Energy Electric Energy Heat/Thermal Energy Kinetic Energy
What are the potential forms of Energy?
Chemical Potential Energy Elastic Potential Energy Gravity Potential Energy Nuclear Potential Energy Magnetic Potential Energy
Explain Conservation of Energy
The law of conservation of energy state that energy can neither be created nor destroyed - only converted from one form of energy to another.
Relate GPE to mass and change in height
- Energy is required for objects to be lifted up from the Earth’s surface against gravity.
- Raised objects are storing gravitational potential energy
- The GPE depends on the mass (Kg) of the objects and how high it is off the ground in metres.
Formula for GPE
GPE=mgh
m= mass g= gravitational force h= height
What is Light Energy?
Energy of Light
What is Sound Energy?
Energy of mechanical vibration
What is Electric Energy?
Energy in opposite electrical charges
What is Heat/Thermal Energy?
Energy of heat (particle movement)
What is Kinetic Energy?
Energy of movement
What is Chemical Potential Energy?
Energy stored in a substance
What is Elastic Potential Energy?
Energy stored in a compressed or expanded item
What is Gravitational Energy?
Energy stored in items depending on their distance from the ground
What is Magnetic Potential Energy?
Energy stored in magnets
