Here we have successfully built up a problem that uses one topic from each of the four quarters of material we have covered. A block with mass m1 = 3.00 kg sits on a horizontal table and is attached to a rope. The rope then passes over a MASSIVE pulley and is attached to a block of mass m2 = 2.00 kg, which hangs vertically (see picture). The coefficient of kinetic friction of the interface between the table and m1 is 0.1. You may assume the pulley section is a disk with a mass of 2.00 kg. We will keep the pulley frictionless for brevity. This time, however, m1 is a piston attached to an isolated volume of air that is heated in such a way that the air is always allowed to expand ISOBARICALLY. The pressure of air inside AND outside the chamber is 1 atm. The initial volume of air is 0.100 m^3 . The cross-sectional area of the m1 piston on either side perpendicular to its motion is 0.0100 meters. a) Find the acceleration of the blocks using Newton’s Laws (no radius needed)
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.
