This means that

Because on a circle

1. the delta-v is represented as the circumference;
2. the time to complete one cycle of motion is represented with a "T," and
3. the acceleration seeks the center and is called a centripetal acceleration,

the formula above is now written as

Two more formulas can now be easily derived by combining the formulas above. By substituting for "v" in the formula above we get

When solving for the centripetal force, use Newton's 2nd Law of motion, F=ma. Because the force is the centripetal force, add subscripts that stand for centripetal. Now the 2nd law looks like this;
