Force Vectors topics include: Coplanar forces, cartesian vectors, dot and cross product.
A force vector is a representation of a force that has both magnitude and direction. A force vector has three components: magnitude, orientation, and sense. The magnitude of a vector is specified by a positive number and a unit. The orientation of a vector is specified by the relationship between the vector and given reference lines and/or planes.
Forces can cause motion or act to keep objects at rest. Forces acting on any object change its movement. The change depends on the strength and directions of forces and on the way the object moved. The formula for solving problems about force is F=ma, where m is the mass of the particle. If a particle is resting in equilibrium then the resultant of all the forces acting on it is zero.
