Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.

Question

You unconsciously estimate the distance to an object from the angle it subtends in your field of view. This angle e in radians
is related to the linear height of the object h and to the distance d by 8= h/d. Assume that you are driving a car and that
another car, 1.50 m high, is 29.0 m behind you.
