All Force Notes

Unit 1 - FORCES

Forces - any straight-line push or pull

A. Representing Forces

1. Units of force

a)  lb. (English)

b) Newton (metric) (weight of 1 apple)

2. Forces are VECTORS

- described using:

- magnitude (size)

 - direction 

Review - Scalar (magnitude only)

ex) time, distance 

Solving problems with vectors require
 a special branch of mathematics

3. When solving problems and drawing pictures, forces are represented as arrows drawn to some selected scale

 
(know your directions)

Scale:  1 cm = 10 N 

F = 40 N East

*Length shows magnitude (size)   

**arrow shows direction
