See what the dot product means: the angle between two directions and the part of a force along a line, drawn in 3D with its perpendicular part and a right-angle mark.

Build a force in space from its components, its three direction angles, two angles or two points, turn the 3D view with the mouse, and add several forces into one.

Write a force by its x and y components, in scalar and Cartesian vector form, and get its magnitude and direction back.

Describe a force in 3D with i, j, k components, its magnitude, coordinate direction angles and unit vector.

Add concurrent forces in space component by component and find the magnitude and direction angles of the resultant.

Write a cable or rope force as a Cartesian vector from the coordinates of two points, using position and unit vectors.
