Consider the pulley system depicted in the figure. The block is prevented from moving by the applied force F. Assume the pulleys are massless and frictionless. T₂ = (a) Determine the tension in each section of rope. (Use the following as necessary: M and g.) T₁ = T₁ T₂ Ts = F= Ts M (b) Find the magnitude of F. (Use the following as necessary: M and g.) (c) What If? What should the magnitude of the force F be if the mass M is to have an upward acceleration of magnitude a? (Use the following as necessary: M, g, and 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.
