1) A 2.0 kg stone swings in a vertical circle on the end of a 1.0 m string. Find the tension of the string at the bottom point if the speed of the stone at this point is 4.0 m/s. 0 12 20 32 52 a) A 0.20 kg stone attached to a string is swung in a circle with a radius 0.60 m on a horizontal frictionless surface. What is the tension in the string if the stone makes 150 revolutions per minute? 0.030 N 0.20 N 0.90 N 2.0 N 30 N b) A 3400 kg plane flying at a constant speed of 170 m/s is to do a vertical loop. What is the radius of the loop if the pilot feels three times his normal weight when he is at the top of the loop? 670 m 705 m 736 m 789 m
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.
