Resultant forces

Loading...

Description

What happens when two or more forces act on an object at the same time?  We could work out the effects of each of these forces one the object separately and then try and figure out the overall effect which they would have on the object, but physicists really love shortcuts, which is where the idea of the resultant force comes in.
