## Can you have net torque with no net force?

Since torque is always about some point, if there’s a net force on an object you can always find some point about which there will be a torque. But you can certainly have a net force on an object that gives no torque about its center of mass.

### What can you say about the body if the net force acting on it is zero?

When the net force of the body is equal to zero, it implies that the body cannot be accelerated. This follows from Newton’s second law of motion.

**Is net torque equal to net force?**

Net torque changes the rotational velocity of an object. Net force changes the velocity of an object.

**Which of the forces do zero torque?**

The magnitude of the torque depends on: An applied force can result in zero torque if there is no lever arm or the applied force is parallel to the lever arm (see Figure 3 and 4 below). Figure 3. Lever arm: these applied forces result in no torque on the wrench because of no lever arm r. Figure 4.

## Can there be torque but no force?

The resultant torque can be either zero or non-zero. Consider a rod. If you exert two forces, equal in magnitude but opposite in direction, to one end of the rod, the resultant force is zero and the resultant torque is zero (because the torques cancel each other).

### Can torque be produced if net force is zero?

Torque on a body can be zero even if there is a net force on it.

**Is the net force always zero?**

When an object moves with constant velocity, the total net force on the object is always zero. If you have applied force, there’s another force (or, many forces) like friction to counterbalance it.

**When body acted upon by no force or by several forces whose vector sum is zero then the body is said to be in?**

Two forces with the same magnitude but different directions are not equal forces. The vector sum of all of the forces acting on a body is a single force called the net force . If the net force is equal to zero, the object is said to be in equilibrium.

## What happens when net torque not zero?

If the net torque is not zero, there will be angular acceleration. It implies the angular velocity will be continuously changing. Conversely, if angular velocity is not changing, that is , if angular velocity is constant, angular acceleration is zero and there is no torque.

### What is the net torque?

The net torque is the sum of the individual torques. Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero.

**When the net force and net torque acts on the body is zero then the body is in?**

Rotational equilibrium

2) Rotational equilibrium: If the net torque acting on a body is zero, then the body is said to be in rotational equilibrium. In such a case, the angular velocity of the body remains constant.
