If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.

Which of Newton's laws of motion is demonstrated when a car applies its brakes on an icy surface but the car continues to slide along the surface?
Newton's First Law: objects at rest tend to stay at rest, objects in motion tend to stay in motion. When the brakes are applied, the friction with the road surface is the force that stops the car -- on ice, this friction is greatly reduced.
What four laws did newton come up with?
If your referring to the 3 laws of newton, the first is that objects at rest tend to stay at rest unless a new force acts upon it, the second is f=ma, or objects in motion tend to stay in motion unless an opposing force acts upon it, and last and possibly most well known (if not in definition then in experience) is that every action has an opposite equal reaction.
What is Newton's first law of motion What term summarizes this law?
newton's first law of motion is; objects at rest stay at rest and objects in motion stay in motion unless an outside force acts upon it. A term that summarizes this law could be that when a wheelchair is standing still, it is not in motion, the only way that the wheelchair can move is unless an outside force (person) acts on it, causing the wheel chair to change distance.
What happens when no force acts on an object?
Nothing changes. When no force acts on an object moving with constant velocity, the body continues its motion with uniform velocity, or if the object is at rest, it will remain at rest.
Does the law of inertia apply to objects at rest?
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."Newton's first law of motion states that "objects in motion stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force." This is also referred to as the law of inertia.
What is friction that acts on objects that are at rest?
Static friction.
Why do objects remained at rest?
As you can observe, they will not ALWAYS be at rest. Objects have a tendency to remain at rest, because:* Inertia means that if no force acts on an object, it will remain at rest if it was at rest; or, if it was moving, it will continue moving at the same velocity. * Friction forces will usually slow objects down.
How do you know that forces are balanced when static friction acts on objects?
Static friction only acts upon objects at rest, otherwise it would be dynamic friction. An object at rest is known to have balancing forces, otherwise it would accelerate. This is Newton's Second Law of Motion.
What friction opposes the motion of sliding objects?
The force that opposes objects already in motion is Kinetic Friction.Static Friction prevents objects from starting to move when originally at rest.
What opposes the motion of one object moving past another?
Friction opposes the motion of one object moving past another. Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a force acts on them.
What is static frictions?
In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. ... The frictional force itself is directed oppositely to the motion of the object.
What can stop inertia?
Inertia is the natural tendency of objects to resist changes in their state of motion. The force of friction brings an object to rest.
How do objects start moving?
Objects start out as either a rest or moving. If they are at rest, they require a force to be applied for them to start moving. If they are moving, they require a force to either slow them down or to make them stop. That means that once something starts moving, it will move forever, unless a force slows it down. The catch is that the force can be friction.
What are the force acting at rest?
It is the gravitational force. Mostly gravity and static friction. Friction is a manifestation of the electromagnetic force.

How much friction acts on the furniture when it is at rest on a horizontal surface?
No friction at all. There are two forces: the Downward force called WEIGHT and the Upward force called the NORMAL FORCE. Since these two are in opposite directions and are, by definition, equal, they cancel out and there is no net force. Because there is no force, there is no acceleration, and in this case where there is no initial movement, the object stays at rest. if there were a frictional force between the object and the surface, it would be in a direction with at least some horizontal component, but since there would be no other force to cancel this out, the object would be accelerating in some direction. It is defined as "at rest", so there is no frictional force. If you were to push the furniture across the surface, then there WOULD be friction to resist the force you were applying. EDIT: This answer is only partly correct. The force of friction is zero if the furniture is at rest. However, if there is a force acting on the furniture that is less than the maximum static friction force (so the furniture still doesn't go anywhere), the force of friction equals the other force.
An object at rest stays at rest until a force acts on it?
Yes. If it is at rest to start with, it will remain at rest until an external force acts on it. Likewise, an object starting in motion will remain in that same motion until an external force acts on it.
