physics
energy
energy stores
types of stores
magnetic
the energy stored when two magnetic poles repel
thermal
energy stored in the form of heat
chemical
the energy stored in a chemical reaction
kinetic
energy in the form of movement
electrostatic
energy from two magnetic poles repel or attract
elastic
the energy stored when a object is streched
gravitational potential
the energy stored when at hight
nuclear
energy stored in the nucleus of an atom
energy transfers
mechanical
a force moving a object
electrical
charges moving due to potential difference
heating
due to a temperature difference
radiation
energy transferred as a wave
work power and efficancy
Work(J) = force(N) x distance(M)
power(W) = work(J) / time(S)
efficiency = useful output/total input x100
energy can be lost and transferred to something that isn't useful
energy demands
kinetic energy = 1/2 x mass x speed2
elastic potential energy = 1/2 x spring constant x extension2
gravitational potential energy = mass x gravitational field strength x height
electricity
electrical circuit
DC
mains electric
Ac- 230v 50hz
equations
charge = current x time
potential difference= energy / charge
power = time x potential difference
power = current2 x resistance
particle model
density
density = mass / volume
Kg/m3 = kg / m3
volume
can be measured with a displacement can and a measuring cylinder
