In this article, you will learn what the resultant force (also known as net force) is, and how to find it when an object is subject to parallel forces as well as non-parallel forces with the help of examples.
When a number of forces are acting on a single object, the forces can be replaced by a single force that has the same effect on the motion of the object as all the original forces acting together. This single force is called the resultant force. The resultant force determines:
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:
The force arising when an object rests against another object acting at a 90° angle to the plane of contact. It is sometimes also referred to as the reaction force. This is normally labelled as N or R on free body diagrams. This force arises from Newton's Third Law.
1. Two horizontal forces act on an object. One is 10 N [W] while the other is 20 N [E 30 N]. Calculate the resultant force on the object. 2. A paddler in a canoe paddles with a force of 200.0 N [E] while the current exerts a force of 100.0 N [E 45 S] on the canoe. Calculate the horizontal force on the canoe. 3.
Resultant Forces. A vector diagram can be used to determine the resultant of two forces that are not acting in a straight line. Worked example 1: ing pulled toward the harbour by two winch motors. Each motor is pulling with a force of 100N . nd they are working at right angles to each othe. Construction lines can be. ZY. The line OZ is the dia.
Resultant Force. Resultant force is the single force that can replace multiple forces acting on an object, producing the same effect. It is the vector sum of all the individual forces, taking into account their magnitudes and directions. In essence, it represents the overall effect of all the forces acting on an object.
