Weight
Weight is the force acting on an object due to gravity.
weight = mass x gravitational field strength
W = mg
Work Done
When a force causes an object to move through a distance, work is done on the object.
work done = force x distance
W=FD
Hookes Law
The extension of an elastic object, such as a spring, is directly proportional to the force applied, provided that the limit of proportionality is not exceeded. Hooke’s Law:
Force = spring constant x extension
F = kx
