Answer :
The line on the graph is slanted and straight. The line shows that the acceleration of the object is constant.
When motion is accelerated continuously, the speed rises by the same amount every second. Free fall is the most illustrative and significant example. Gravity causes a steady acceleration when something is thrown or dropped; this acceleration is roughly 10 meters per second squared.
Your velocity will always change if your acceleration is constant, but it will change steadily over the course of each second. Despite the fact that zero is a constant, zero acceleration is still zero acceleration.
Theoretically, a particle's velocity should not fluctuate over time if it is moving at a constant speed. The acceleration at that point is known as zero acceleration.
