What kind of friction causes a box you are pushing across the floor to stop when you stop pushing?

Answer 1

is it gravity,friction,inertia or balanced force

All surfaces, even highly polished metal surfaces, are covered with microscopic dips and bumps. When two surfaces are in contact, the surfaces stick to each other where the dips and bumps on one surface touch the dips and bumps on the other surface. Friction is caused by the sticking of the two surfaces at these bumps and dips.

Static friction occurs when the force applied to an object is not large enough to break the connections between the surfaces. When the force applied is strong enough, the connections are broken and the object starts sliding. As the object slides, new connections are continually being formed and broken. The formation of these new connections between the sliding surfaces causes sliding friction.

GravityOne non-contact force you are very familiar with is gravity. Gravity is a non-contact force that every object exerts on every other object due to their masses. You and this book both have mass. As a result, you exert a gravitational force on this book, and this book exerts a gravitational force on you. In the same way, you and Earth exert gravitational forces on each other.

The gravitational force between two objects is an attractive force that tends to pull the two objects closer together. You've experienced this attraction when you fall to the ground after jumping upward. The size of the gravitational force between two objects depends on the masses of the objects and the distance between them. The gravitational force between two objects increases if the mass of one or both of the objects increases. If two objects move closer together, the gravitational force between them increases

Answer 2

Static friction
