1. Scalar and vector quantities

2. Scalar quantities Are quantities that have magnitude but no direction
Such as: speed, density, area

3. Vector quantities
Are quantities that have both magnitude and direction
Such as velocity, forces, acceleration
To determine the resultant of a vector quantity use the parallelogram law

4. Parallelogram law
Step 1. draw the vectors to scale at the specific angle
Step 2. draw lines parallel to the forces
Step 3. complete using the arrows the resultant vector
Step 4. determine the value of the resultant vector using your ruler and scale outlined.
