The impact force with which a 1 Newton apple hits the ground depends on the height from which the apple falls and the stopping distance after impact. Since the weight of the apple is already provided, the apple is no longer in free-fall, and the answer is 1 Newton.
Continue ReadingThe apple fell from a height of zero in order for it to be described as 1 Newton. In general, impact force is a product of the work done and the time it takes to slow the object down. The work is the energy needed to slow the object down. To minimize damage to the falling object, the time to slow the object down should be as large as possible.

Full Answer >Isaac Newton's theory of gravity states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The law is represented as: F=G (m1m2)/R.
Full Answer >The force of gravity between two objects can be increased by reducing the distance between them. The force of gravity is influenced by the masses of the two objects and the gap between them. Gravitational force generally increases as objects become more massive and draw closer together.
Full Answer >A moment arm is the distance between the joint axis and the line of force acting on the joint; an example is using a wrench to loosen a nut, the wrench acts as a moment arm and produces more force than trying to free the nut by hand. In physics, the product of force applied multiplied by the moment arm results in torque.
