what is a resultant force?
the single force that can replace all the individual forces acting on an object and have the same effect
No resultant force acts on the body…
When the balanced force is produced
equilibrium
an object is in equilibrium if the resultant force is 0 or if the forces are balanced
what is work done?
work is done on an object when a force causes it to move through a distance. energy is also transferred
equation for work done
work done (J) = force (N) x distance (m)
