elasticity - hooke's law
-
when an object is stretched and returns to its original form, it has been elastically deformed
if the object does not return to its original form, it has been inelastically deformed. The extension of the object no longer follows hooke's law
-
-
resultant forces
when one or more forces act upon an object, these forces can be treated as a single force, having the effect of all of them combined
vector diagrams
vector diagrams are drawn to determine the size and direction (vector) of the overall resultant force (a combination of all active forces)
the forces are represented as arrows, and are drawn connected to each other, from the point of one arrow to the base of another
work done
when a force causes an object to move, work is done on the object
-
when work is done, energy transfers take place within the system
-
gravity
the force of attraction between all masses. the gravity that affects an object is dependent on its mass and the gravitational field strength that surrounds it
