Weight is the result of...
Gravity
How much you eat
Forces acting on you
How tall you are
Weight =
mass x gravitational field strength
gravitational field strength + mass
Mass ÷ gravitational field strength
Gravitational field strength ÷ mass
Work Done = Forces ÷ Distance Moved
Power is
the rate at which work is done
how strong you are
how many times the amount of work you can do
the potential amount of work you can do
Power =
Work done ÷ Time Taken
Time taken ÷ Work done
Time taken x Work done
