# If a book remains stationary on a table are the forces acting upon the book in equilibrium?

the book cannot change its direction of motion

### If an object is stationary the forces acting upon it are?

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.

### Static equilibrium and dynamic equilibrium?

Static Equilibrium: If some forces are acting on a body horizontally or vertically, and the body remains it states of rest is called Static Equilibrium. Formula: ∑Fx =0 ∑Fy =0 Example: a book lying on a table. Dynamic Equilibrium: If some forces are acting on a body horizontally or vertically, and the body remains it states of motion is called Dynamic Equilibrium. Formula: ∑ =0 Example: a train is moving with uniform 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.

### If an object is not moving usually there are what forces are acting on it?

If an object is not moving or if it is moving with a constant velocity (meaning there is no acceleration), the sum of the forces acting on it is equal to zero. A stationary object is said to be in static translational equilibrium, while an object with a constant velocity is said to be in dynamic translational equilibrium. Typically, an object at rest on the ground has two forces acting on it: Gravity and the…

### Explain when a matter is in a state of equilibrium?

It is in equilibrium when the two conditions are satisfied - there is no net translational equilibrium and no net rotational equilibrium. For translational equilibrium, the summation of forces acting on the matter must equate to zero, which means that there is no resultant force. For rotational equilibrium, the sum of moments must be zero, which means there is no resultant torque. When these two conditions are met, the object will be stationary, i.e. 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…

### When two opposite forces acting on an object are equal they are what?

Two equal forces (equal in magnitude and direction) result in simply double each individual force. However, if the forces are acting opposite to each other they will cancel each other out and they cause a resultant force of zero. This means the object is in linear equilibrium and is either moving at a constant speed or is stationary.

### Can an object that has balanced forces acting on it be standing still?

If there are any forces acting on a stationary object, then they must be balanced, or it would no longer remain stationary. It is also possible that the object is already moving. In the forces are balanced on a moving object, the object would continue moving at the same speed and direction (velocity) that it already had.

### What does the term balanced forces mean?

If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
