What is the accelaration of a body that is subjected to imbalanced force equal to its weight?
When you talk about weight and forces you have to conclude that you are dealing with a falling body, and that other forces such as air resistance etc are ignored: Now your question: If a body is falling towards the earth it experiences a downward force equivalent to its weight: that is mass of the body multiplied by the acceleration due to gravity. Unbalanced or Resultant force on body = mass * acceleration. This is measured in N As an example, a 100kg man will have a downward force acting on him of 981N This force is in actual fact an unbalanced force acting downwards, and the acceleration will be 9.81m/s³ As far as I can determine, the only possible way that an unbalanced force equal to the weight of the man can affect the acceleration is if a further 981N foce is applied downwards on the man. The total force acting downwards on the man will then be 1,962N, and his acceleration downwards will be 19.62m/s². If a 981N force is applied upward on the man, he will stop falling, his veloci
