Abstract

The motion of material bodies is studied depending on the forces acting on them. Forces in the dynamics of the variables may depend on time, position of the body, and its velocity. You can come to the concept of inertia if you want to compare the results of the action of one force with different bodies. The property of bodies to change their speed faster or slower under the action of applied forces is called inertia. A quantitative measure of inertia is the mass of a body (a measure of the gravitational properties of a body). The mass of this body will be considered constant (with the exception of specially discussed cases). To distract from the shape of the body, the concept of a material point is introduced. A material point is a material body that has a mass, the size of which can be ignored when studying motion. In dynamics, a body moving translationally can be considered a material point. Dynamics are based on the laws that Newton laid out in 1687. These three laws are also called the Galileo-Newton axioms, since the first law was discovered by Galileo in 1638.
