energy transfer
druringprocess useful things happen
transferred by chemical reactions
energy is never lost or made
only transferred
tracking the process is used the energy transfer diagram
sanky diagram is a energy transfer diagram
show the energy transferred by each device
useful and non useful energy
dynamos
convert kinetic energy
rely on magnetism
used wire between two
used to be operated by water power or steam
used to run electricity in richvictorian houses
investigating fuels
nitrogen and natural gasses are highly explosive
combustion depends on
the amout of fuel
how much energy is stored in the fuels
fuels it most chemical energy
graps are useful to compare energy data for different fuels
different graphs show data in different ways
difference between temperature and heat
temperature
use decrees celsius°
use termometer
0° to 10°
a mesure of energy of the individual particles
heat flow
when there is a difference between two object heat will flow to the colder
the heat will always go to the colder
heat is total energy of each particle
potential and kinetic energy
gravity
gravitational potential energy
higher the object is the more gravitational potential energy has
when object falls energy is transferred by kinetic energy
the bigger the thing who produces gravity the more gravity is produced
tranferred by movement & heat
the fastest the object falls the more energy is transferred by heat
whan you lift weights you transferr engergy
the work done depends on the size of the force applied
work done= force x distance
lever makes a weight lighter
if a girl is lifting a rock
force is f
the work done by girl on lever f1xd1
so
word done by girl on the lever = work done by the lever on the stone
f1xd1=f2xd2
work done by the lever to stone
f2d2
