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.

n 3 of 11 Mickey, a daredevil mouse of mass M, is attempting to become the world's first "mouse cannonball." He is loaded into a spring- powered gun pointing up at some angle, and is shot into the air. The gun's spring has force constant k and is initially compressed a distance X from its relaxed position. If Mickey has a constant horizontal speed V while he is flying through the air, how high above his initial location in the gun does Mickey soar?
