Yes, if an object has a constant acceleration, it means that there is a net force acting upon it. This is described by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The equation can be written as:
F = ma
Where: F is the net force acting on the object, m is the mass of the object, and a is the acceleration of the object.
If the acceleration is constant, it implies that the net force acting on the object is also constant. In other words, there is a constant force acting on the object, which causes it to accelerate uniformly.
