QUICK QUIZZES 1. Newton`s second law says that the acceleration
... Newton’s second law says that the acceleration of an object is directly proportional to the resultant (or net) force acting on. Recognizing this, consider the given statements one at a time: (a) True— If the resultant force on an object is zero (either because no forces are present or the vector sum ...

... 3. Choose a point around which rotation can occur. (Amazingly, there can be several such points, each producing a unique solution method toward the same set of answers.) 4. Identify the torques, lever arms and angles of torque action. 5. Forces at the point of rotation (fulcrum) have no torque. Why? ...

Artificial gravity
Artificial gravity is the theoretical increase or decrease of apparent gravity (g-force) by artificial means, particularly in space, but also on Earth. It can be practically achieved by the use of different forces, particularly the centripetal force and linear acceleration.The creation of artificial gravity is considered desirable for long-term space travel or habitation, for ease of mobility, for in-space fluid management, and to avoid the adverse long-term health effects of weightlessness.A number of methods for generating artificial gravity have been proposed, as well as an even larger number of science fiction approaches using both real and fictitious forces. Practical outer space applications of artificial gravity for humans have not yet been built and flown, principally due to the large size of the spacecraft required to produce centripetal acceleration.
