Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Force diagrams and resultant forces Learn about drawing and interpreting force diagrams. Find out how to calculate resultant forces acting on an object.

Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object. Show the forces acting on an object in a free body diagram. The ...

When solving problems, draw arrows on your diagrams to show forces acting on an object. The length of the arrow can represent how strong the force is, and the direction shows where it’s pushing ...

Figure 1: Anomalous lateral force in the helix particle–substrate configuration. We first show the full-wave numerical results of the optical forces acting on helical gold particles induced by a ...
