Step-by-step explanation:
Acceleration is the rate of change of velocity. Velocity is a vector quantity that includes both speed and direction. If an object is moving in a straight line at a constant speed, it has a non-zero speed, but its velocity remains constant. Since acceleration is defined as the change in velocity over time, and there is no change in velocity (both magnitude and direction remain constant), the acceleration is zero.
In simpler terms, an object can have speed without experiencing acceleration if its motion is uniform, meaning it maintains a constant speed and moves in a straight line. This is a key concept in physics, especially when considering objects in equilibrium or those moving with constant velocity. In such cases, the absence of acceleration implies that no net force is acting on the object, or that the forces acting on it are balanced.
