    Answer:

    Energy is conserved.

    Explanation:

    According to law of conservation of energy ,energy can neither be created nor be destroyed .

    When the player kicks the soccer ball, the kinetic energy is transferred to the ball and it will roll for a while and then stops. The combination of force and distance is called as work.Greater the force faster the ball will go.

    The force with which the soccer player player kicked the ball will be having it effects on the ball. As the ball rolls in the ground  kinetic energy which the ball got from the player will be lost in the form of heat due to friction.

    According to the Newton first law of motion,the object continues to remain  in rest or move with constant speed unless acted upon by the external force.
