How can you calculate the resultant force acting on an object?

• A. By subtracting all individual forces
• B. By vectorially adding all individual forces
• C. By averaging all forces acting on the object
• D. By multiplying all individual forces

Answer: (B)

The resultant force acting on an object is determined by vectorially adding all individual forces. This method takes into account both the magnitude and direction of each force applied to the object. Forces are vectors, which means they have both size (magnitude) and direction. When multiple forces act on an object, their effects can be combined using vector addition, which is crucial for obtaining the correct resultant force. For example, if two forces are exerted on an object in opposite directions, the resultant force will be the difference between the two forces and will act in the direction of the larger force. If forces are applied at angles to each other, it is essential to break them down into their components along the axes (usually horizontal and vertical) and then add these components separately. This vectorial addition ensures that both size and direction are appropriately considered, yielding an accurate resultant force that indicates how the object will move according to Newton's second law of motion.
