Vectors

We started the day off by correcting the Kinematics pracitce quiz.

Then we started our new unit on Vectors.

The difference between vectors and scalor quantities is

Vectors

• need a direction

Scalor Quantities

• consist of a magnitue (ex. 6kg or 42m/s)
• the units have to be the same

We then took notes as an intro to vectors. The key points of these notes included.

• A vector is composed of a line segment drawn to scale with an arrowhead at one end.
• The length of a vector symbolizes its magnitude, and the arrowhead its length.
• The direction of a vector always need to be put in squar brakets.

KEY TERMS

Collinear Vectors are vectors that exist in the same dimension.

Equivalent Vectors are a special type of collinear vectors that are equal in magnitude and direction.

Non-Collinear Vectors are vectors that exist in more that one dimension.

We finished off the day practicing drawing vectors.

Brianne is next.
