If two forces are acting in a straight line (parallel), then we can work out the resultant force very easily: If the forces are acting in the same direction, we add them to find the resultant force. If the forces are acting in the opposite direction, we subtract them to find the resultant force.
A resultant force is the overall force that acts on the object. Remember that forces are vectors. When you calculate the resultant force you need to also say the direction it is acting in.
• There are two methods to draw force vector diagrams: • The Tip-to-Tail Method, where you align the vectors tip to tail and construct the resultant force by joining the free ends. • The parallelogram method. Where you place the vectors tail to tail, construct a parallelogram and measure the diagonal that now represents the resultant force.
A resultant force is a single force that describes all of the forces operating on a body. When multiple forces act on one object, the forces can be combined to produce one net force that describes the combined action of all of the forces. This single resultant force determines:
