Chapter 6
Vectors
A vector quantity is a quantity which is fully described by both magnitude and direction. On the other hand, a scalar quantity is a quantity which is fully described by its magnitude.
A force is a push or pull exerted by one body on another. Sometimes two or more forces act on a body at the same time. The result of this action is called the resultant force. If the resultant force is zero, then the body experiences no net force (no movement).
This is called equilibrium, remember Newton's Laws,
presenting no movement. Vectors are used to graphically represent forces. Their
angle specifies the direction of the force, and their length specifies the
magnitude of the force. Vectors can be graphically combined to determine the
resultant force when two or more forces are acting on a body.

You type in the measurements of the vectors and the angles then the computer program will do the mathematics automatically and will give you the length and angle of the resultant.

This would be very helpful in correcting since one can punch in the degrees and lengths of certain vectors and the thing will calculate the resultant and degree of the angle.
