Scalars: Quantities with only magnitude. (Normal Numbers) Can just be added. Examples: time, mass, energy, distance, speed

Vectors: Quantities with both magnitude and direction. Examples: Displacement, velocity, force

 Finding Resultant: Must be added “tip to tail“, using scale model or components.

Resultant: The vector formed by adding two vectors.

Maximum resultant is when vectors are pointing in the same direction. Add the magnitudes.

Minimum resultant is when in opposite direction. Subtract magnitudes.

x- and y- components of vectors.- Use trig to find. Usually Ax = Acosθ and Ay = Asinθ
