Introduction
The addition of
vectors can be done using the triangle law of vector addition or by using the
Parallelogram Law.
Pre-Requisites:
Vectors, Scalars,
Vector Addition, Parallelogram Law, Triangle Law, Head to Tail Method
Activity:
Triangle law of
vector
Real Life Question:
When two or more
forces act on a body, how do we know the resultant force?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Parallelogram Law | If two vector quantities are represented by two adjacent sides or a parallelogramthen the diagonal of parallelogram will be equal to the resultant of these two vectors. |
| Triangle Law | If two vector can be represented both in magnitude and direction by the two sides of a triangle taken insame order , then their resultant is represented both in magnitude and direction by the third side of a triangle taken in opposite direction . |
