3:21 - Start of Seesaws Moments

3:24 *the pivot is the Middle* 3:26 *apply the first force on the seesaw*
3:30 *the perpendicular distance, which is between the pivot and the force, is for the first force on the seesaw*
3:40 *the Moment/the working out for the first Force*
3:47 *anticlockwise and clockwise*
NOTE:
it is defined *anticlockwise* and *clockwise*
rather not define UP and DOWN on the Pivot Seesaw
3:57 *first force is an Clockwise moment*
4:04 *apply the second force on the seesaw*
4:07 *second force is also an Anticlockwise moment*

4:11 *explaining the overall working out of the Seesaw for the Moment answer*

4:21 *what happens when the seesaw is balanced*

4:37 (what im left on and doing more notes later)
