Introduction
The position of any
point on XY plane can be represented with a position vector. Displacement is the
shortest distance between the initial and final points.
Pre-Requisites:
Vectors, Components
of Vectors, Vector Resolution, Position Vector, Displacement, Displacement
Vector
Activity:
Observe the map of
your city and see the route you take when you go to school. Appreciate that
your displacement from your home, is nothing but the length of the straight
line drawn from your home to your school. That line is a vector which points
from your home to your school.
Real Life Question:
How to represent any
point on a plane using vectors?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Position Vector | The position of any point on XY plane can be represented with a vector with respect to origin. This vector is the position vector. |
| Displacement Vector | Displacement is a vector which has its tail at the initial point and its head at the final point. |
