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?
Girlneedinghelp
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?
Equal forces acting on an object in opposite directions are called balanced forces. If they are on the same line of action, they are called couple forces.
Balancing the forces acting on an object give you the net force?
If the forces acting on an object are perfectly balanced, the resulting net force is equal to zero.
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.
What is the relationship of forces acting on a body?
The forces are vectors, the vectors are added together, therefore forces acting against each other will cancel each other out, forces acting in the same direction will add up. For forces acting in different directions you can use Pythagorean theorem to add them up. The sum is what gives the body an acceleration, depending on it's mass. ( F=m*a )
What are equal forces acting on an object in opposite directions?
Equal forces acting on an object in opposite directions are called balanced forces. If they are on the same line of action, they are called couple forces.
Is it possible for an object to not be in motion and still have forces 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.
When a ball is at rest all the forces acting on it are?
Equal.
When combined forces acting on an object does not equal zero?
In that case, the forces are said to be unbalanced.
What is the expression for equilibrium?
the sum of all forces acting on an object should be equal to zero the sum of all forces acting on an object should be equal to zero
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.
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).
Balancing the forces acting on an object give you the net force?
If the forces acting on an object are perfectly balanced, the resulting net force is equal to zero.
What does it mean if a cell is in the equilibrium?
It means that all forces acting on it are equal.
How can forces acting on an object be unbalanced?
If the sum of the forces on an object do not equal zero, then the object will experience acceleration.
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.
Are 2 forces going in the same direction balanced?
No, they are not. The forces are balanced only when forces of equal magnitude are acting in the opposite direction.
