When torque is zero which quantity remains constant?

angular momentum
If the net torque is zero, then angular momentum is constant or conserved.

Under what condition a torque acting on a body is zero?

That is, when line of action of forces passes through the axis of rotation, torque is zero.

Which of the following quantity is zero if torque on a particle is zero?

Explanation: Torque is defined as the rate of change of angular momentum. So, if torque is zero, the rate of change of angular momentum will be zero.

How do you know if net torque is zero?

If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.

When a torque acting on a system is increased then which one of the following quantities will increases *?

the time derivative of angular momentum is equal to the torque acting on the particle. For a given change in linear momentum when time of impact increases force .

What remains constant in SHM?

Solution: The only thing that remains constant for one particle performing SHM is its periodic time or simply time period.

When the net torque acting on a system is zero Which of the following will be constant a force B angular momentum C linear momentum D none of these?

Explanation : When the torque acting upon a system is zero, the angular momentum is constant and hence is conserved.

How can torque be 0?

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).

What happens to a body when a steady torque is acting on it?

Continues in its state of rest or uniform motion along a straight line.

How do you get zero torque?

When a torque acting on a system is zero then which of the following should not change?

When the total external torque acting on the system is zero, then the total angular momentum of the system is conserved.
