Question

Asked Sep 30, 2019

An apple falls from a tree and strikes the ground without bouncing. What happens to its momentum? Is momentum conserved?

Step 1

The system’s (Earth + apple) initial momentum is zero. When the apple falls towards the Earth, it gains momentum as the Earth’s gravitational force pulls the apple towards itself. Also, the apple applies an equally opposite force on the Earth. However, since the Earth’s mass i...
