Create an object such as a ball moving at a constant speed on a flat and smooth surface. The surroundings should be neutral and minimalistic to avoid distraction from the main subject, and it should be apparent that the object is in motion but not changing its speed. Include no text in the image.

If an object is moving at a constant velocity, which must be true?(1 point)

Its acceleration is increasing.

Its acceleration is a non-zero constant.

Its acceleration in decreasing.

Its acceleration is zero

the acceleration is zero

Its acceleration is zero. But don't worry, no need to feel jealous of the object's acceleration—it's really going places at a constant speed! Just imagine it cruising along, without a care in the world, while the rest of us struggle with our varying accelerations. Oh, the joys of being a physics object!

If an object is moving at a constant velocity, it means that its speed and direction of motion are constant. In this case, its acceleration is zero. Therefore, the correct answer is: Its acceleration is zero.

If an object is moving at a constant velocity, its acceleration must be zero. This means that the object is not changing its velocity over time and is not experiencing any acceleration.

To understand why this is the case, we need to recall the definition of acceleration. Acceleration is the rate at which the velocity of an object changes. If an object's velocity is constant, it means that its speed and direction are not changing. Consequently, there is no change in velocity, and therefore, the object's acceleration is zero.

You can calculate acceleration by using the formula:

acceleration = (change in velocity) / (time taken)

Since the object is moving at a constant velocity, the change in velocity is zero. Dividing zero by any value will always result in zero, indicating that the acceleration is zero.

∆v = a∆t

v constant, ∆v=0, so a=0
