 understand:
1. The change in motion of a body is the result of interaction with other bodies. If no forces act on a body it kinematics characteristics remain constant.
2. The measure of interaction between bodies is force.
3. Kinematics characteristics of the body can be constant during interaction with other bodies. It takes place if the sum of all forces equals zero.
4. All dynamics laws and kinematics characteristics are stated relative to the definite frame of reference.
5. Newton’s Laws are valid in all inertial frames of reference.
6. Galileo’s transformations are used at transition from one inertial frame of reference to other.
7. The laws of mechanics have the same form in all inertial reference frames.
8. Relativity principle of mechanical motion in classical mechanics is based on statement that mass, size of bodies and time interval between events don’t depend on velocity of reference frame motion.
