energy Flashcards
examples of chemical energy =
food and fuel
examples of kinetic energy =
in moving objects
examples of gravitational potential energy =
in objects that are raised
examples of elastic energy =
in stretched or compressed objects
examples of thermal energy =
in any heated objects
examples of magnetic energy =
in any object with a magnetic field.
examples of electrostatic energy =
electrostatic forces between charges.
examples of nuclear energy =
the forces acting between atomic nuclei
work (J) =
Force (N) x distance (m)
energy transferred (J) =
Charge flow (Q) x P.D (v)
Kinetic energy (J) =
0.5 x mass (kg) x speed^2 (m)
Elastic potential energy (J) =
0.5 x spring constant (N/m) x extension^2 (m)
G.P.E (J) =
mass (kg) x gravitational field strength (N/Kg) x height (m)
the amount of energy required to raise the temperature of 1Kg of a substance by one degree Celsius =
specific heat capacity
change in thermal energy (J) =
mass (kg) x specific heat capacity (J/Kg °c) x temperature change (°c)
