when we are moving the force act there but when we are in uniform motion does the force is 0 and not
Answers
A perfectly smooth surface would mean no friction so that force is out. If it is on a surface, then there must be gravity between both objects. This means there is some force! The key is that the gravity force attracting the object and the surface together is balanced by the repulsive force of the outer electrons around all the atoms of both the object and the surface. All matter is surrounded by negative electrons so all matter tends to repel other matter when thing get close together.
So there are two forces - gravity and electrostatic repulsion but they are balanced. Newton’s law says that balanced forces do not produce acceleration so the constant speed of the object remains constant.
F=m*a here in uniform motion acceleration is zero so force is 0 but we work against some resistance like gravity so we have to maintain some accelaration
