y = kx ie y/x = k, k = 2, so y = 2x
displacement = (final velocity square + initial velocity sq. )/ 2 * acceleration
the for loop is basically a repitation or traversing loop means one's to write his name 100 times he use the for loop example for(i=0;i<=100;i++) { printf("my name is AA"); } the for loop checks the condition until i<=100 repeates the name or check the condition upto 100 times and then terminates.
