Vector Diagrams
free body diagram - a diagram used to show different forces acting on an object
(rest in text book, better to look at than make notes on)
Resultant Forces
Resultant force - when more than one force acts on an object,, these forces can be seen as a single force that has the same effect as all the forces acting together
Forces & Elasticity
To change the shape of an object, more than one force must be applied.
If the object returns to its original shape after the forces are removed, it was elastically deformed
If the object does not return to its original shape, it has been inelastically deformed
