Question

what is the acceleration of an object moving at a constant speed ?​

Answer 1

To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion to a straight path. Newton's second law (F=ma ) suggests that when a force is applied to an object, the object would experience acceleration

Answer 2

The slope of the line gives the acceleration of the object. On a velocity vs time graph, a line of constant slope indicates that the object has uniform (constant) acceleration. A horizontal line (a slope of zero) indicates that the object has zero acceleration and is moving at constant velocity.
