summary of the video with the time for reference:
1.Force 1:07
Push or pull on an onject
F=m x a
Weight = mass x g(9.8)
2.Vector 1:47
-Tells us point of action
-Magnitude is told by length of the arrow
-Tells us about the direction of Force
3.Force System 3:20
-Linear force system 4:04
-Forces are co planar and co linear
-if extended they overlap each other
-basic addition or subtraction
-compressive or distractive force
-Concurrent force system 5:50
-Vectors are not colinear and coplanar
-Parallelogram method is used to find out the resultant force
-Finding out the parallel and perpendicular components
-eg 1.weight on the leg
-eg 2.shoulder joint
-eg 3.Knee joint
