Draw 2u+4v. First, you have to exert enough force to actually move the door, but that's only part of the story, the magnitude part. In the diagram, vector a represents the speed and direction of the boat relative to the water, and vector b represents the speed and direction of the current. Understanding the differences between vectors and scalar quantities. Take the example of a scaler like 20 miles per hour. Let's take for example a helicopter, you may notice when helicopters go up and down they are completely vertical right?But when they want to go forward they need to actually tilt, that's to create this thrust where they're pushing air in that direction which is causing a force in that direction. IV. Now if that was my only force acting on that ball that would be a pretty good shot right. Are, Learn The resultant vector is the vector that 'results' from adding two or more vectors together. If vector A lies in the third quadrant, its direction will be: a) 180 − b) 360 – c) 180 + d)none .
