1.2.Kinematic equations of motion of a material point

Lecture



When a material point M moves, its coordinate   1.2.Kinematic equations of motion of a material point and radius vector   1.2.Kinematic equations of motion of a material point change over time t.

Therefore, to specify the law of motion, m. you must specify either the type of functional dependence of all three of its coordinates on time:

  1.2.Kinematic equations of motion of a material point (1.2)

or the time dependence of the radius vector of this point

  1.2.Kinematic equations of motion of a material point (1.3)

The three scalar equations (1.2) or their equivalent single vector equation (1.3) are called the kinematic equations of motion of a material point.
