Scalars and Vectors in Statics

What makes force a vector, how vectors are drawn and written, and how free, sliding and fixed vectors differ.

Dot Product Visualizer: Angles and Projections in 3D

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.
