The static friction acting on an object is higher compared to the dynamic friction, between two surfaces. One has to overcome this force to move an object.
When an object is to be moved from rest, you have to use a force F1 to overcome friction (static) to displace it and give it an initial velocity & acceleration.
When an object is moving already on a surface, to increase its speed, you have to use force less than F1 to increase speed by the same amount in same time.
When an object is rolling like a wheel (rotating) , the frictional force is even less compared to the other frictional forces.
