Unformatted text preview: very similar manner the acceleration of the object can be calculated: (13a) (13b) The direction and magnitude of the acceleration vector are: (14) (15) Equation (14) shows that the direction of the acceleration is in the radial direction (opposite to the position vector). See also Figure 4.4. Note: Equation (12) shows that the magnitude of the velocity of the object is constant (independent of time). Equation (11) shows that only its direction changes with time. Note: Equation (15) shows that the acceleration is nonzero. It is clear that this nonzero acceleration does not change the magnitude of the velocity, but it changes its direction. The acceleration will be nonzero if either the magnitude or the direction of the velocity changes....
