Answer to Question #165652 in Field Theory for Aliyah

Question

On day with no wind, a large is dropped from a tall buildingThe object experience air resistance during its fall to the ground. State and explain,in terms of the forces acting, how the object varies during its fall

Answer 1

Answer

According to concepts of physics

As the object is released two forces act on it.Its weight and and air resistance in air. At this point its weight is much greater due to the force of gravity on the object so it accelerates downward. As its speed increases so does the drag on the object so its aceletation starts to slow down until it reaches zero. At which point air resistance will be equal to the weight of the object leaving a resultant force of zero.
