Non-Free-Fall Motion and Newton's Second Law of Motion
In the image below, we are again looking at the man the instant he leaves the plane.
If we know the mass of an object, we can find the force due to gravity acting on that object any time the object is at or near the surface of the earth. Fill in the blanks below to find an equation for the force due to gravity acting on an object with a given mass at or near the surface of the earth.
