Function
Intended for experimental study, physics laboratory and carrying out physics experiments on: Statics. The composition of concurrent coplanar forces, with 90° to each other. Force and vector. What is meant by vector. Characteristics of a vector. Graphical representation of a vector quantity. Collinear vectors and coplanar vectors. The resulting vector. Operations with coplanar and non-parallel vectors. Orthogonal coplanar vectors (perpendicular to each other), a special case. Types of force. Measuring the total weight of masses. The composition of concurrent coplanar forces, with 60° to each other. Remembering collinear vectors and coplanar vectors. Non-orthogonal coplanar vectors, parallelogram rule.
