## Does an object in equilibrium have a net force of zero?

Because **there is no net force acting on an object in equilibrium, then from Newton’s first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion.**

## What is the net force of an object that is in static equilibrium?

In a static equilibrium, all the forces balance each other and object is either not moving or moving with uniform velocity and hence **net force is zero .**

## What are the requirements for an object to be in total static equilibrium?

To achieve complete static equilibrium, a system must have **both rotational equilibrium (have a net torque of zero) and translational equilibrium (have a net force of zero). translational equilibrium: A state in which net force is equal to zero.**

## What two conditions must be met for an object to be in static equilibrium?

Conditions for equilibrium require that **the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.**

## Is an object with zero net force in equilibrium?

A body is said to be in equilibrium if **the net force acting on the body is zero. By Newton’s second law, the acceleration of such objects will be zero. So an object in equilibrium can either have zero velocity or a constant non-zero velocity.**

## What net force does an object in equilibrium have?

0 Newtons

## What are the forces in static equilibrium?

An object is in static equilibrium if and only if: **The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero (i.e. it’s not moving).**

## Does static equilibrium have a net force of 0?

If the object is in static equilibrium, then it is **experiencing zero net force, which means that no matter what reference point we choose, the net torque will be the same.**

## What happens when an object is in static equilibrium?

An object in static equilibrium is **one that has no acceleration in any direction. While there might be motion, such motion is constant. Two children on a seesaw: The system is in static equilibrium, showing no acceleration in any direction.**

## What are the two requirements for an object to be in equilibrium?

For an object to remain in equilibrium, two conditions must be satisfied – **both the net force and the net torque must be equal to zero. An example of an object in equilibrium is a rod that is free to rotate about a hinge at one end.**

## What does the total force have to be for an object in equilibrium?

For an object to be in mechanical equilibrium, the net external force and the net external torque acting on the object have to be **zero. F**tot 0, u03c4tot 0.

## What are the three conditions of equilibrium?

**A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply :**

- The lines of action are coplanar (in the same plane)
- The lines of action are convergent (they cross at the same point)
- The vector sum of these forces is equal to the zero vector.
