What can you say about the forces acting on a stationary object?

The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.

∙ 11y agoThe force of gravity on the object in that situation is the same as it is in any other
situation on the Earth's surface. But there is another force acting on the object, in
the direction opposite to the gravitational force, called the "buoyant" force. If the
object is floating, then the two forces are equal in magnitude and, being opposite
in direction, they add up to zero. With zero net force acting on it, the object has
no tendency to accelerate vertically, so it stays wherever you put it.

If a crate is stationary on an incline does it mean that it is in the state of equilibrium?
If a crate placed on an inclined plane is moving at constant velocity or not moving at all -- which is really a special case of constant velocity where the velocity is zero -- then the sum of the forces acting upon it is zero. We can say that it is in a state of equilibrium, where all forces acting upon it are in perfect balance and cancel themselves out. A free-body diagram is often used to represent a body and the forces acting upon it and helps us visualize the relationship of the vector forces. See this link: http://en.wikipedia.org/wiki/Free-body_diagram#Example

What does it mean to sat that the net force determines an objects acceleration?
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
What does Newton's second gas law state?
To say in simple language, Issac Newtons second law is F= Mawhere "F" is ForceM= Mass and "a" is accelerationThe sum of the forces on an object is equal to the total mass of that object multiplied by the acceleration of the object. In more technical terms, the acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Thus, F = ma, where Fis the net force acting on the object, mis the mass of the object and ais the acceleration of the object. Force and acceleration are both vectors (as denoted by the bold type). This means that they have both a magnitude (size) and a direction relative to some reference frame.
How can an object have forces acting on it but not accelerating?
If all forces in all direction on an object are equal then a box diagram would show that the forces (newtons, N) will cancel each other out, so it will stay fixed in it's positionIf the forces are imbalanced then you can achieve acceleration. So for a car to move it must overcome tyre friction, so heat and noise wastage, air resistance, and all the smaller forces trying to stop the engine moving (mostly friction). Once it produces more force than those require it can move.No. A balanced group of forces has the same effect on an object as no force at all.
Can you say about the no forces acting on a stationary object?
If the object is not moving, then the only thing you can be sure of is that since it's not accelerating, all of the forces acting on it add up to zero. Just the fact that it's not moving is not enough information to tell you that there are no forces on it.
If an object is moving at a constant speed what do we know about the forces acting on the object?
Not much, really. If the object's direction is changing, then the velocity changes, and there are forces acting on it. The only thing we can say is that the net force acting on the object is either zero, or it is perpendicular to the movement.If the VELOCITY doesn't change, then the net force (the sum of the forces) is zero.
What is the total of all forces acting on an object called?
The total of all the forces acting on an object is called either the metabolism respiration enzymes or photosynthesis
What type of force does an object have if its net force is equal to zero?
If the net force on an object is zero, we can say that the forces are balanced, or that they are in equilibrium(which really means the same thing). There may be forces acting on the object, but there is an equal and opposite force pushing or pulling in the opposite direction, and all the forces balance out. Alternatively, there may be no forces acting on the object at all.
When is the net force equal to the sum of the individual forces?
That's the definition of "net force", so you might say "always". This refers to forces acting on the same object. If there are time-varying forces, the answer might be never!
What object has all forces acting on it?
Please redefine question. All objects have all forces acting on them to some degree or another, with strong and weak nuclear forces, gravitational, electromagnetic being the fundamental forces. Or do you mean something like uniform compression forces, say of a submersible underwater being "crushed from all sides".
The force of gravity acting upon the mass of an object?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
What is the force that opposes frictional force?
Say you are moving an object against the carpet flooring, you are the force and you are causing the object to move as well as you are creating friction between the carpet and the object. The force would be called the netforce, which is all the forces that are acting on an object.
What is the net force equation?
It means the same as the sum of all the forces acting on an object. Note that since forces are vectors, they have to be added as such. For example, an book resting on a table has gravity pulling it down; on the other hand, the table is pushing the book upwards (by Newton's Third Law; since the book pushes down on the table). Adding all the forces together, you get a zero force - which must be so, for the object to remain at rest.
Is an object is stable what we can say about this object's force?
If an object is in static equilibrium (or "stable"), there is no net force acting on the object.
What is it when you add two forces acting on an object?
Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates. Obviously, if they're the same size and opposite in direction, providing the body is rigid (it doesn't deform, in other words), the stat of motion of the body will stay the same (either at rest or moving at a steady speed in a straight line).
If there are two equal and opposite forces on something you say the forces are?
If the forces are balanced they will have no action or the object, if not they will accelerate the object in the resultant direction of the two forces..
