It offers great flexibility and precision for handling both analytic surfaces defined by common mathematical formulae and modeled shapes.
In addition, the experiment produces data which the students plot to learn how to make graphs. Learn about position, velocity, and acceleration vectors. In non uniform circular motion, the size of the velocity vector speed changes, denoting change in the magnitude of velocity. The velocity vector is tangent to the trajectory at each point and, in addition, its magnitude changes evenly with time. Nonuniform circular motion in all strictness, we have derived the expression for radial acceleration for uniform circular motion the derived formulae actually apply for nonuniform circular motion, as long as the radius of the trajectory is constant.
