Some of the time, for example when the things are too small, classical mechanics is not good.

Our focus will be classical mechanics and Newton's three laws.

By the end of the 20th century, classical mechanics in physics was no longer an independent theory.

In classical mechanics this is known as a normal mode.

Because of this, they are a very useful tool in classical mechanics.

As a second step, the limit must be taken to recover classical mechanics.

However, in classical mechanics one usually makes these decisions directly by comparing forces.

Analogy with classical mechanics shows that the following is a way to complete the theory.

In classical mechanics the force is often the gradient of a potential energy.

In its usual presentation, classical mechanics appears to give time a special role.
