second video review
GEARS CAN BE OF ANY SIZE OR A SHAPE AND THEY ARE MEASURED USING TEETHS.SPEED OF GEARS MATTER ALOT BECAUSE IT DOES’NT MATTER IF GEARS ARE BIG OR SMALL.

third video review
it was about torque 
force and axis you need force to move any object.

video # 2
it was about sizes of gears how they effect rotation and direction and speed different gear ratios have different effects

video # 3
it was about torque and the main element was force .

half of the circle is diameter and half of diameter is radius the outer boundary of circle is called circumference

review of video # 2
it was about the different sizes of gears and their combinations called gear trains how they affect speed and direction

review of video # 3
 
force torque and axis all three are resonsible for the working of gears

radius=1/2 d
the outer boundary called circumference
area = pie * r^2

gears video:

gears ratio
12 tooth gear
24 tooth gear
36 tooth gear how the effect direction and speed

torque video 

torque depends on force and we also watched axis

it has circumference which is the outer boundary 
half of the circle is diameter and half of the diameter is radius

video # 2
gear trains and different sizes of gear were responsible for the change of speed and directions


video #3
force and momentum are the basic component of torque and torque is involved in gears
