1. Vectors

2. Vector and Scalar quantities
Scalar quantities have size or magnitude, but a direction is not specified.
(temperature, mass, speed, etc.)
Vector quantities have magnitude and a specific direction (velocity, acceleration, etc.)

6. The Resultant Vector
The resultant is a vector that represents the sum of two or more vectors.

7. One way to find a resultant could be to draw the situation to scale on paper (such as 50 m = 1 cm).
Measuring the length of the vector pointing from the tail of the first vector to the head the second vector, and then, multiplying by the scale .
For example if line (c) is 3.0 cm the distance would be 150 meters This is the displacement.

9. Using Pythagorean theorem to find a resultants magnitude.
A toy car is moving directly across a moving walkway. As the car moves in the y direction, the walkway moves in the x direction.

We can look at the diagram as a triangle. Therefore we can solve this by using the Pythagorean theorem.
