    It also has a rotational velocity caused by the centripetal force acting toward the center of the circle. Hence, the resultant velocity of the body is the sum of the tangential and rotational velocities keeping the body at the circumference of the circle as trajectory of the motion. Now let's consider the motion of the insect. The only force keeping the object on its circular track is the force of gravity, which means that at the apex, the speed of the object has to be such that the centripetal force equals the object’s weight to keep it going in a circle whose radius is the same as the radius of the loop.
