How do you know the forces acting on an object at rest are balanced?

Its been awhile since I've done physics so correct me if im wrong. I believe you have the downward force of gravity (obviously). And u also have the upward force of the ground (confusing i know but i think i remember this as true. Its what keeps the car from going underground). Like i said, it has been awhile since I've done physics so I could be way wrong.

How do you know if the net forces on an object are balanced or not?
If the vector sum is zero. In other words, if the componens of force add to zero it is balanced.
Is pushing a box but it doesnt move a balanced or unbalanced force?
There's no such thing as a balanced force or an unbalanced force.If the entire group of all the forces on an object is unbalanced, then the objectundergoes acceleration, or its "motion changes". If the group of forces on it isbalanced, then its motion doesn't change.
What does the motion of an object look like after the forces acting on it end?
We don't know what the forces were or in what direction, and we don't know anything about the object. So we have no idea what its motion looks like when the forces end. But we do know that whatever speed it has and whatever direction it's moving at the instant the forces stop, it'll continue in the same direction at the same speed from then on.
How do you find out if a force is balanced or unbalanced?
Its easy....To balance force you need to apply an equivalent force in the opposite direction....Example:If a force of 20N acts on a body along the North, you should apply 20N along the south......simple.......
Are geologic forces still acting on earth today?
Yes. But how do u know?
How do you know that the forces acting on an object are balanced?
The object will be in both rotational and translational equilibrium and will not be moving.
When an objects motion changes you know that the forces acting on it are?
Not balanced. The net force acting on the object is not zero.
When an object is at rest what are the forces acting on it?
You never know. The only thing you know about the forces on an object that's not accelerating is: They all add up to zero, and their effect on the object is the same as if no forces at all were acting on it. That's the same as saying that all the forces on the object are 'balanced'.
What term best describes the forces acting on an object with the net force of zero?
An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
How can you tell if a force is balanced or unbalanced by looking at it?
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.
How do balanced and unbalanced forces affect the motion of an object?
Objects move according to their net force, or the total amount of force acting on them. Balanced forces are just that, balanced. An object with balanced forces will not move because the opposing forces will cancel each other out. However, if there are unbalanced forces, the object will move in accordance with the force that is greater. When moving though, there is always friction. Whether you be underwater, on the ground, or in the air there is always friction on the Earth. (Besides vacuums, of course.) Force is equal to mass x acceleration. With that you can find the forces of the object if you know its mass and acceleration.
If the net force On an an object is zero what do you know about all of the forces acting on the object?
Net force is a combination of all the foces acting on an object.If two forces are acting in the same direction you add the forces to calculate the net force
What occurs in an objects position when acted on by an unbalanced force?
First of all, there's no such thing as an unbalanced force. A group of forces maybe balanced or unbalanced, but the forces themselves aren't.An unbalanced group of forces acting on an object causes the object's velocityto change. That means the speed or direction of its motion changes. It doesn'ttell you anything about the object's position. In order to figure that out, you'dhave to know what its speed and direction were before the unbalanced groupof forces began acting on it, and you'd also need to know the object's mass.
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.
How do you know if the net forces on an object are balanced or not?
If the vector sum is zero. In other words, if the componens of force add to zero it is balanced.
When there are several people acting on an object and it starts to roll what do you know about the forces acting on the rock?
You know that the combined force is enough to overcome the force of friction.
What are the 2 forces acting on a sinking object?
There are 3 (I am doing physics IGCSE and my paper says state the 3 forces acting on a sinking anchor), but I only know one, upthrust!
