Question: 1 / 2700

If a vehicle travels at a constant speed on the highway, what can be said about its acceleration?

Its acceleration rate is positive

Its acceleration rate is zero

When a vehicle travels at a constant speed, it means that its velocity is not changing over time. Acceleration is defined as the rate of change of velocity. Since the vehicle maintains the same speed, there is no change in velocity, which means the acceleration is zero. This condition occurs regardless of whether the vehicle is moving forward or in a straight line; as long as the speed remains constant, the acceleration will not be increasing or decreasing. This concept is fundamental in physics, as it emphasizes the relationship between speed, velocity, and acceleration.
