@d!_†oX!©:
i am quoting this from the IGCSE Physics Study Guide
" When the force is perpendicular to motion, the object follows a circular path."

Can someone explain me how and why????

Ghost Of Highbury:
refer to the diagram

wassup:

try this, hope u get it.

@d!_†oX!©:
dude i already know all this...
wat i am asking now is for example....
when the force acting on the planets in the solar system, is directed towards the sun rite???
then why does it not move towards it rather than the real situation where it moves around it!!!!!!
do u now get what i mean by my question???????

Mutual gravitational forces accelerate the earth as it exerts comparitively less gravitational force on the SUN. here, the large gravitational force of the sun allows the earth to take a circular path, unlike its conventional straight path. The planets relative to themselves are acyally following a straight line.
