Question

in vertical circular motion controlled only by gravity speed of an object is​

Answer 1

Answer:

Unlike horizontal circular motion, in vertical circular motion the speed, as well as the direction of the object, is constantly changing. Centripetal forces cause centripetal accelerations. In the special case of the Earth's circular motion around the Sun – or any satellite's circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.
