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.
Know MoreThe 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 >The force of gravity is an attraction that pulls all matter together. Matter is inherently attracted to other matter, due to the force of gravity. As more matter binds itself together, it exerts more gravity.
Full Answer >An upward force is any force that counteracts the force of gravity. Buoyancy is an example of an upward force because it pushes an object away from the Earth's center of mass.
Full Answer >A force meter is a device comprising a hook and spring that measures force. The standard international unit of force is the newton.
