Study route
18.1 Vector kinetics
- The position of the material point sets the radius-vector, the change is displacement, the instantaneous velocity is directed in tangential direction, the acceleration describes the change of the velocity vector.
18.2 Movement of body at an angle
- Without air resistance, the horizontal projection of speed is constant, and the vertical change under g. The combination of the two movements gives parabola.
18.3. Traffic relationship
In a classical mechanic, the speed of a body relative to one system is equal to the vector sum of its speed in a mobile system and the speed in the system itself.
