The roXXXXXXXX (or XXXXXXX) acceleration XX XXXXXXX XX XXX XXXX XX XXXXXX in XXXXXXXXX or XXXXXXXXX of the XXXXXXX velocity. The acceleration XXX both XXXXXXXXXX (point XX XXXX XXXXXXX straight XXXXX) XXX Perpendicular (XXXXX XX XXXX XXXXXXX XXXXXXX XXX center of XXXX) components.
XXX Tangential component means "how XXXX XX XXX insect's velocity changing in XXX direction directly ahead XX it". This XXXXXXXXX will be XXXX, since the XXXXXX XXXX not change speed and XXXXX XXX XXXXXX XXXX XXX stop "XXXXX XXXXXXX/XXXXXXXX ahead" or XXXXXX XXXXXXXXX XX jumping to the side or something XXXXXXX XXXX XXXX. XXX XXXXXXXX, XX you XXX running on a circular track, you are XXXXXX XXXXXXX "XXXXXXXX XXXXX" not XXXXXX XXXX XX side, usually at a constant XXXX.
XXX Perpendicular component means "how much XX XXX XXXXXX's XXXXXXXX changing in XXXXXXXX XX XXX XXXXXX of the XXXX". Again, the XXXXXX XXX disc's XXXXXXX XXXXX (i.e. magnitude XX XXXXXXXX) are constant and XXXXX. So XXX insect does XXX change speed. However, XXX insect'sdirectionof XXXXXXXX XX XXXXXXXXX at XXXX XXXXXX, with respect XX XXX center XX XXX disc. XXX XXXXXX's XXXXXXXXX repeatedly changes XXXX XXXXXXX XXXXXXX XXX center.
XXXXXXXXXX acceleration = Tangential + XXXXXXXXXXXXX components
XXXXXXXXX, XXXXX XXXXXXXXXX = X, XXX XXXXXXXXXXXXX ≠ X. XXXXXX XXXXXXXXXXXX ≠ X means XXXXXX XX XXXXXXXXXXXX
