Heat energy-the transfer of thermal energy, particles move faster
Solar energy-energy from the sun
chemical energy-energy stored in particles of matter (batteries, sugar, food)
electrical energy-energy flowing in an electric circuit
generator-produces an electric current when a coil of wire wrapped around an iron core is
rotated near a magnet, power plants
solar cells-can be used to convert solar energy to electrical energy
mechanical energy-energy due to the motion (kinetic) and position (potential) of an object
potential energy-stored energy
kinetic energy-energy an object has due to its motion
transformations-can occur between the two types of mechanical energy, changing from one to
the other
rubber bands- when stretched they have potential energy, when let go, they have kinetic
energy
electric circuit-a loop in which electricity is able to flow
wire-conductor of electricity
battery-contains stored chemical energy
light energy-electrical energy is changed to energy in a light bulb
sound energy-electrical energy is changed into sound, like a radio or tv
heat energy (transformation)-electrical energy is changed into a heat source, like an oven or
toaster
mechanical motion-electrical energy is changed into ______ by a fan or motor
magnetism-the force of attraction or repulsion of magnetic materials
magnetic field-a field that applies a force, a push or pull, without actually touching an object
electric current-can form from a coil of wire spinning around a magnet or a magnet spinning
around a coil of wire
electromagnets-formed when a wire in an electric circuit is wrapped around an iron core
producing a magnetic field
water-can power turbines, wet
wind-can power turbines, air
steam-can power turbines, hot air
simple motors-changes electrical energy to mechanical energy
conduction-transfer of heat through touch
convection-transfer of heat through air or liquid, rising and falling
radiation-transfer of energy through space without particles of matter colliding or moving to
transfer the energy
work-means to apply a force to an object over a distance and the object moves in response to
the force
force-push or pull
newtons-SI units that measure force
spring scale-measures force
lever-a rigid bar or board that is free to move around a fixed point called a fulcrum
pulley-has a grooved wheel with a rope running along the groove
effort force-the amount or direction of the force applied to the object
inclined plane-a sloping surface, like a ramp, that reduces the amount of force required to lift
an object
fulcrum-a fixed point in which a lever can move freely
tweezers-kind of lever, think unwanted hair
scissors-kind of lever, think to cut
wheelbarrow-mix of wheel and axle and a lever, think leaves
fixed pulley-attached to a structure, can be found on the top of a flag pole and on window
blinds
moveable pulley-not attached to a structure, can be found on construction cranes, part of a
block and tackle system
wedges-inclined plane, like a knife-blade
ramps-inclined plane, sloping surface
screws-inclined plane wrapped around a post or cylinder
wheel axle-door knobs, steering wheels, gears
complex machine-consist of two or more simple machines
compound machine-another name for complex machines
bicycle-example of a complex machine, takes you places
