A source that will naturally replenish itself
What is renewable?
Stored in nucleus of atoms
What is nuclear energy?
Water rushes in and turns a turbine changing kinetic energy to mechanical
Mechanical turns to electric with power generatior
What are the steps of hydro electric power plants?
any device that makes doing
something easier
machine
A flat sloped surface
Inclined plane
Will be gone forever after use
Energy that is only available in limited amounts or that is used father then it is replenished
What is nonrenewable?
Energy stored in the
chemical bonds between atoms
Nuclear fusion in nuclear energy becomes thermal energy and heats water to create steam
Steam makes mechanical energy by turning a turbine
Turbine turning turns the mechanical energy into electrical
What steps do nuclear power plants take for power?
Grooved wheel with a rope or cable wrapped around it
Pulley
____= Force x Distance
What is the equation for work?
Solar power can never be used up
What is inexhaustible?
Energy due to motion. The faster it is the more it has.
Kinetic energy
Turn chemical energy into thermal energy by burning the coal which heats water and makes steam
Steam spins in a turbine, changing thermal into mechanical energy
The turbine spins a generator, turning mechanic into electrical energy
Simple machine made up of a bar that pivots, or rotates, about a fixed point
lever
wedge
Sloped surface that moves
Fossil fuel
stored energy due to the
interactions between objects or particles. Has three main types
What is potential energy
Hot geothermal heat heats the water creating steam with thermal energy
Thermal energy to mechanical, the steam turns a turbine
mechanical energy to electrical from a electric generator
What steps are taken to power hydrothermal energy?
Point about which a lever pivots
fulcrum
ratio of the output work
to the input work a percent
what is effiency?
Biomass
What is an example of an renewable source?
Due to the energy to the kinetic energy or motion of atoms or particles in an object
What is Thermal energy
1. wind spins blades, turning kinetic to mechanical
2. turns to electrical with generator
What are the steps to generate energy with winds?
An axle attached to the center of a wheel and both rotate together
Wheel and axle
Output over input force
Mechanical advantage
