What are the two forces acting on a person as they move up and down in an elevator and when are these two forces equal and when are they not equal?
When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.

What are equal forces acting on an object in opposite directions?
When equal forces act on an object in opposite directions, they create a state of balance known as equilibrium. This means that the object will not accelerate in any particular direction, but remain stationary or move at a constant velocity.
If a box has equal and opposite forces acting on it will the box accelerate?
No. To have an acceleration, you need a non-zero NET FORCE. That is, the sum of all objects acting on the box must not be equal to zero.
How do you equal and opposite forces acting on objects can produce vastly different accelerations?
They can't. The vector sum of equal and opposite forces is zero, and they can't produce any acceleration at all.
Balancing the forces acting on an object give you the net force?
Yes, balancing the forces acting on an object involves ensuring that the sum of all forces is zero, which means there is no net force acting on the object. This equilibrium condition results in the object either remaining at rest or moving at a constant velocity.
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.
Are resultant forces acting in different directions equal?
No, resultant forces acting in different directions are not equal. The resultant force is the net force that results from combining all the individual forces acting on an object, taking into account their direction and magnitude.
When combined forces acting on an object does not equal zero?
In that case, the forces are said to be unbalanced.
Is it possible for an object not to be in motion and still have a force acting on it?
Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.
What are equal forces acting on an object in opposite directions?
When equal forces act on an object in opposite directions, they create a state of balance known as equilibrium. This means that the object will not accelerate in any particular direction, but remain stationary or move at a constant velocity.
Do all forces acting on objects cause motion?
If the forces acting on an object are equal there is no motion (5N->O<-5N). If the forces are unequal there is movement (7N-->O<-5N).
What does it mean if a cell is in the equilibrium?
It means that all forces acting on it are equal.
What is the net force on an object that is acted on by balanced forces?
If all forces acting on the object are balanced (equal), the net force acting on the object is zero.
Is it possible for an object to not be in motion and still have forces acting on it?
Yes, it is possible for an object to not be in motion and still have forces acting on it. This situation could occur if the forces acting on the object are balanced, resulting in a state of equilibrium where there is no net force causing motion.
What will be value of tension produced by two opposite forces acting on a string at opposite ends?
equal to zero because two opposite forces will cancel each other
What does it mean if forces are equal?
If forces are equal, it means that they have the same magnitude but opposite directions. This results in a state of equilibrium, where there is no net force acting on the object.
When an object is in rest all the forces acting on it are in what?
All the forces acting on each other are in equilibrium. For instance the restoring force upward from the ground/floor is equal to the strength of the force of gravity, which acts downwards.
When two forces P and Q acting along the same line then its resultant?
The resultant of two forces P and Q acting along the same line is the algebraic sum of the two forces. If they are acting in the same direction, the resultant is equal to the sum of the forces. If they are acting in opposite directions, the resultant is equal to the difference between the two forces.
