Kinetic Friction replaces Static Friction when an object is in motion.
Static friction, which is DEFINED as the friction there is when the object doesn't move. Instead, there is dynamic friction, which is usually less.
dynamic friction
If you push an object, it starts moving. Good examples (in the sense of not having static friction, which may hinder movement totally if the force is not strong enough) are a person sitting on a swing; or a boat in water.If you push an object, it starts moving.

Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
what starts to move an object is force because it's pushing on the object and what stop's the obect from moveing is force too because if the force is going the oppisit way its going to stop the object.
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
Because if you push a car(toy car) and it starts to slow down then it is because of the friction from the wheels between the track. And if thee car does not slow down then it is because the slope is going diagnal and in the same nonstop speed. DOH

Friction is holding immobile objects in place.
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
There are two main types of friction: kinetic and static. Static friction resist impending motion: the force needed to break before something starts sliding. Static friction stops acting upon the object once it starts moving. Kinetic friction resist motion: the force that is opposing existing motion, i.e. object has already started sliding.

Friction always acts in a direction opposite to the direction of motion. When to push or pull an object, friction manifests in a direction opposite to motion and the frictional force is dependent on the characteristics of the surfaces. When the push or pull force is slowly increased, at a certain point the frictional force is overcome and the object starts moving.
The only thing that can do that is force.
