Let's start with the simple case in which an object is subject to two forces that act in the same direction: The resultant force is in the same direction as the two forces, and has the magnitude equal to the sum of the two magnitudes:
Let's consider the case in which an object is subject to two forces that act in opposite directions. If the two forces are equalin magnitude: The resultant force will be zero because two opposite forces cancel each other out. On the other hand, if the two forces are not equalin magnitude: The resultant force will be in the same direction as the for...
Let's now consider the case in which an object is subject to more than two parallel forces: To find the resultant force in this case, we first sum all the forces that go in one direction, and then all the forces that go in the other direction: At this point, we have two forces that are in opposite directions, which is a case that we already know ho...
In the previous cases, we have forces that are all parallel to one another. It's time to consider the case in which an object is subject to two forces that are not parallel. For example, let's assume that we have a block subject to two forces, F1 and F2. F1 has magnitude 50 N and is applied at a 45° angle, whereas F2 has magnitude 60 Nand is applie...
Finally, let's examine the case in which an object is subject to more than two non-parallel forces. For example, suppose we have an object that is subject to three forces, F1, F2, and F3. The magnitude of each force is shown below: The free-body diagram of the object looks like this: We can find the resultant force Rusing the same process that we u...
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...
In physics and engineering, a resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body via vector addition. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces. [ 1 ]
In summary, the resultant is the vector sum of all the individual vectors. The resultant is the result of combining the individual vectors together. The resultant can be determined by adding the individual forces together using vector addition methods.

What is resultant force? If multiple forces act at the same point, we can consider them as one single force that has the same effect as all the original forces acting together. This new force is called the resultant force. So the resultant force is a sum of all the forces acting on an object.
