If there is a friction force there would be negative acceleration? Or positive acceleration?

If there is a friction force acting on an object, it would typically result in a negative acceleration. This is because the friction force acts in the opposite direction to the motion of the object, causing it to slow down or decelerate. Positive acceleration would occur if there were no opposing forces acting on the object, allowing it to speed up or accelerate in the direction of the applied force.
