By reference to the pattern of the lines of gravitational force near to the surface of the Earth, explain why the acceleration of free fall near to the Earth’s surface is approximately constant.
The detailed solution steps are locked. Click on the blue button to unlock them.
The gravitational field lines are approximately parallel and evenly spaced near the Earth's surface. Therefore, the gravitational field strength near the Earth's surface is approximately constant, hence, the acceleration due to gravity remains approximately constant near the Earth's surface.
