* J = F*d = applying 1 newton for 1 meter (units of kg * m²/s²) | * J = F*d = applying 1 newton for 1 meter (units of kg * m²/s²) | ||
* F = J/d | * F = J/d | ||
+ | * Work is positive if it is applied in the same direction as movement | ||
+ | * No (net) work is done moving an object horizontally some set distance (unless you overcome friction) - it does not gain or lose potential energy, or have increased kinetic energy at the conclusion | ||
* power = work/time (joules/sec or watts) | * power = work/time (joules/sec or watts) | ||
