The ability to do work.
A force applied over a distance. For formulae, see work done by a constant
force parallel to displacement and work done by
any constant force, and
work done by a position-dependent force.
The units of work, equivalent to a Newton-meter. Also units of energy.
The energy of motion.
Work done per unit time. For formulas, see Formula for average
Definition of instantaneous power, and formula
Unit of power; equal to joule/second.
Work done by a constant force parallel to displacement
||W = Fx|
Work done by any constant force
||W = Fx cosθ|
||W = ΔK|
Formula for average power
|| = |
Definition of instantaneous power
||P = |
Formula for instantaneous power
||P = Fv cosθ|
Work done by a position-dependent force
||W = F(x)dx force.
