Topic 1.1: Scalars and Vectors in 1 Dimension

Front

What are scalars?

Back

Scalars are quantities described by magnitude only.

Front

What are vectors?

Back

Vectors are quantities described by both magnitude and direction.

Front

How can vectors be visually modeled?

Back

Vectors can be visually modeled as arrows with appropriate direction and lengths proportional to their magnitude.

Front

Give examples of scalar quantities.

Back

Distance and speed are examples of scalar quantities.

Front

Give examples of vector quantities.

Back

Position, displacement, velocity, and acceleration are examples of vector quantities.

Front

How are vectors notated?

Back

Vectors are notated with an arrow above the symbol for that quantity.

Front

Is vector notation required for vector components along an axis?

Back

No, vector notation is not required for vector components along an axis. In one dimension, the sign of the component completely describes the direction of that component.

Front

How are opposite directions denoted in a one-dimensional coordinate system?

Back

Opposite directions are denoted by opposite signs.
