Show SUN EFFECTS EARTHS ORBIT Centrifugal Tendency Prevents Planet from Being Drawn Directly Toward To-ward the Center of Attraction Tho earths motion Is tho resultant of component forces These forces are first gravitation or tho attraction attrac-tion of tho sun for thy earth second the momentum of the earths mass which Imparts to the earth the centrl fulgal tendency or the tendency to fly off Its orbit In the direction of the tangent The attraction of tho sun for tho earth provents the tangential motion while tho centrifugal tendency ten-dency prevents the earth from being drawn directly toward the center of attraction In tho illustration reproduced here at tho points B and D the suns attraction at-traction Is the samp and the earths velocity is the same but tho direction direc-tion of the earths movement Is not tho same at both points that is to say the centrifugal tendencies at these two points arc different At Bowing B-owing to the action of component forces which have brought it to that point the resultant tendency Is slightly slight-ly towards the sun with an increasing velocity At D however tho direction direc-tion of motion is slightly away from the sun and therefore since tho component com-ponent forces namely the attraction of tho sun and the centrifugal motion at D are different from those at B B A 0 The Earths Orbit then the resultant motion is different differ-ent The difference In motion then is caused by tho difference In centrifugal centri-fugal tendencies at tho two points |
