Final answer:
The statement is False. An object with constant acceleration does not have constant velocity; instead, the velocity changes by a constant amount over time.
Step-by-step explanation:
If an object moves with constant acceleration, its velocity must be constant? The answer is False. If an object is moving with constant acceleration, by definition, this means that the rate at which its velocity changes is constant, not the velocity itself. To clarify, constant acceleration implies that the velocity of the object changes by the same amount every second.
For example, if a car accelerates at a constant 3 meters per second squared, this means that every second, the car's velocity will increase by 3 meters per second. After one second, the car's velocity may be 3 m/s, after two seconds 6 m/s, and so on, indicating that the velocity is not constant but increasing linearly over time.
Therefore, the statement that an object's velocity must be constant when it experiences constant acceleration is not true. The object's velocity is changing at a steady, unchanging rate.
