A Description of Kinematic Laws

Kinematics, division of physical science and a branch of classical mechanics concerned only with the physically possible motion of an object or system of objects without considering the internal forces involved (i.e. forces that cause the bodies to be in motion and their relative positions in space). A brief discussion of kinematic systems follows. In simple kinematic systems all forces acting on the object cause its motion. There is no concept of resistance or a force of attraction.

This definition includes all forces that cause the system of objects to be in one state or another and does not include forces such as gravity, which are thought to be part of kinematic systems. Thus, kinematic systems are just as good at describing how objects move as are other types of theories. The theory of conservation of energy states that the total amount of kinetic energy is equal to the total amount of potential energy in a system. This theory applies equally to objects and systems. It is widely accepted and used to describe the laws of physics in general, but it is not a universally accepted theory.

Conservation laws of motion are necessary for any description of real-world systems and the analysis of experiments. In particular, the conservation laws of motion provide an account of why objects remain at constant relative speeds as time passes. The general purpose of such laws is to enable us to predict the motion of objects in terms of time.

As mentioned above, the first law of kinematic systems is that there are no external forces acting on the objects are always at rest. This statement can also be written in terms of second order laws. In terms of first order laws, the objects are always in a state of conservation of momentum or energy. Conservation of energy states that the total quantity of kinetic energy is equal to the total quantity of potential energy. A description of this type of law of conservation of energy may also be written as a law of conservation of energy.

The second law of kinematic systems is called conservation of angular momentum. This law states that there is a conservation of angular velocity in any two objects when one object is spinning on the axis of rotation about the other. It is a form of conservation of momentum in its purest form. If this law is valid, it implies that the objects will remain in an identical position as long as they are spinning around the axis of rotation. It is a useful source of information for determining the direction of an object in space.

The third law of kinematic systems, the conservation of momentum, is the second form of first order law. This law says that the energy of motion is conserved when the objects move in a straight line from one point to another. This type of law may also be written as a first or second order law. A description of this law of conservation of momentum may be written as a third order law. A description of this type of law may also be written as a second order law.

The fourth law of kinematic systems is called conservation of energy. This law states that the total quantity of potential energy is equal to the total quantity of kinetic energy. This law may also be written as a second or third order law. It applies to a point particle in space or to a whole system.

The fifth law of kinematic systems is called conservation of angular momentum. and states that if the initial velocity of an object is greater than the velocity at which it reaches, then it continues to go to the right. If the initial velocity is less than the velocity at which it reaches, it continues to go to the left. It is often used as a means of finding the direction in which an object is traveling.
