One of the most important Problem in three-dimensional motion is that of a mass moving under the action of a central force inversely proportional to the square of the distance from the center. The conservation laws for angular momentum and energy are consequences of the large degree of symmetry. Actually exploring symmetries and their consequences is essential in the search for the laws of physics. The central force problem is good example for investigations of symmetries and conservation laws. Although some difficulties ate expected making high school students understand. it seems desirable to give them a flirty good intuitive feeling for the connection between symmetries and conservation laws.
