force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

this experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet falls between

Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts

One day he discovers an unmarked journal with no name‚ which depicts sadistic animal torture experiments‚ boasts of arson fires‚ and the planning for the serial killings of three women. Duncan decides to make amends for his failure last summer by tracking down the owner of the journal by using clues left hidden in the diary. After talking with his

The History of Classical Gravitational Theory and General Relativity In the beginning scientists and religious men of their era tried to explain the universe both biblically and scientifically. One of the foremost Greek scientists was Aristotle; taught by Plato‚ that the circle and sphere are the two most perfect shapes in a 2 and 3 dimensional universe‚ Aristotelian system placed Earth at the center of the universe; and all other heavenly bodies revolved around the earth in crystalline orbitals

Motion-Force and Acceleration The Big Idea: An object accelerates when a net force acts on it. 6.1 Force Causes Acceleration • Unbalanced forces acting on an object cause the object to accelerate. • The combination of foces acting on an object is net force; acceleration depends in net force. • Doubling the force on an object doubles its acceleration. • An object’s acceleration is directly proportional to the net force acting on it. 6.2 Mass Resists Acceleration •
