A bucket full of water is revolving in a vertical circle of diameter 1.4m. a) Draw a labelled force diagram for the bucket full of water at the highest point of the motion. b) Using the Newton's 2nd law calculate the minimum speed at the highest point of vertical motion of the revolving bucket when water in the bucket didn't spilled out at that point. (take, g = 9.8 m/s²). c) Calculate the centripetal force acting the bucket full of water at the highest point fthe 'hucket full of water' is 2500 grams.
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.
