When a net torque is applied to a rigid object it always produces a
1. constant acceleration
2. rotational equilibrium
3. constant angular velocity
4. constant angular momentum
5. change in angular velocity
5. change in angular velocity (and angular momentum)
3. constant angular velocity
When a rigid body is being rotated, every particle within the body will rotate in the same direction, while retaining its original shape. The omega(angular velocity) will remain the same.
When a net torque is applied to a rigid object, it can produce several different effects depending on the circumstances. The correct answer is:
5. change in angular velocity
Applying a net torque to a rigid object can cause it to change its angular velocity. The change in angular velocity can either be an increase or decrease, depending on the direction of the torque and the initial conditions of the object. Torque is the rotational equivalent of force, and it causes rotational motion in an object. So, when a torque is applied, it can accelerate, decelerate, or reverse the rotation of a rigid object.
When a net torque is applied to a rigid object, it can produce various effects depending on the circumstances. Let's go through the options to determine the correct one.
1. Constant acceleration: This is not always the case. If the object has a constant moment of inertia (resistance to rotational motion), then a constant torque can result in a constant angular acceleration. However, if the moment of inertia changes, the object's angular acceleration will also change.
2. Rotational equilibrium: This is not correct. If a net torque is applied to a rigid object, it means there is an imbalance of torques acting on the object, which leads to a rotational motion rather than equilibrium.
3. Constant angular velocity: This can be true if the net torque acting on the object is zero. In the absence of a net torque, the object will maintain a constant angular velocity due to the conservation of angular momentum.
4. Constant angular momentum: This is not correct. Angular momentum is conserved in the absence of a net torque, but if a net torque is applied, the angular momentum of the object will change.
5. Change in angular velocity: This is correct. When a net torque is applied to a rigid object, it will generally result in a change in angular velocity. The magnitude and direction of the angular velocity will be influenced by the net torque, the moment of inertia of the object, and the duration over which the torque is applied.
To summarize, the correct answer is 5. Change in angular velocity. When a net torque is applied to a rigid object, it typically produces a change in the object's angular velocity.
