Work (in terms of energy)
A measure of the energy transferred from one store to another
Work (in terms of forces)
When the force causes a displacement of the object
W = Fd
The equation linking work, force and distance (moved in the direction of the force)
W
The symbol for work
F
The symbol for force
d
The symbol for distance
Joules (J)
The SI unit for energy and work
Newtons (N)
The SI unit for force
Metres (m)
The SI unit for distance
What one joule is equal to
The amount of work done done when a force of one newton causes a displacement of one metre (1 J = 1 Nm)
Newton-metre (Nm)
An alternative unit used to measure the work done by a force
Effect of doing work against friction
Work done against the frictional forces acting on an object causes a rise in the temperature of the object
