1. First, find the x-component and the y-component for each vector.
2. Get the total x-components.
3. Get the total y-components.
4. After getting the total of x and y component. Apply the Pythagorean Theorem or apply the sine or cosine law depending on the problem needed.

1. Plot the points based on the distance and direction given.
2. Measure the distance using the scale that is easy for you.
3. Measure the angle formed or given.
4. Connect the point of origin to the last point of the vector to get the resultant vector.
5. Measure the distance from the first vector to the last point of vector and also the degrees formed.

Scalar Quantities

Most of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy.

Vector Quantities

A vector quantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis.

**Vector and Scalar quantities is our assigned topic. This lesson isn't really new to me but it is interesting to know more things about it.
