oncepts & Calculation Centripetal Force Ball A is attached to one end of a rigid mass-less rod, while an identical ball B is attached to the center of the rod. Each ball has a mass of m=0.50kg, and the length of each half of the rod is L=0.40m. This arrangement is held by the empty end and is whirled around in a horizontal circle at a constant rate, so each ball is in uniform circular motion. Ball A travels at a constant speed of vA=5.0m/s. Find the tension in each half of the rod? How many tension forces contribute to the centripetal force that acts on ball A? How many tension forces contribute to the centripetal force that acts on ball B? Is the speed of ball B the same as the speed of ball A?
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
