When an object is moving at a constant velocity, the acceleration of the object is zero because the change in the velocity of the object is zero.
Acceleration is defined as the change in velocity per change in time of motion.
The acceleration of an object is calculated as;
[tex]a = \frac{\Delta v}{\Delta t } = \frac{v_2 - v_1}{t_2 - t_1}[/tex]
When an object is moving at a constant velocity, the change in the velocity of the object is zero.
[tex]v_2 = v_1\\\\a = \frac{v_2 - v_1}{t_2 -t_1} = \frac{v_2 - v_2}{t_2 -t_1} = 0[/tex]
Thus, we can conclude that when an object is moving at a constant velocity, the acceleration of the object is zero because the change in the velocity of the object is zero.
