Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis,fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist.In more basic terms, torque measures how hard something is rotated
Centripetal force is a force that makes a body follow a curved, as opposed to straight, path; it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path.

Do internal forces which are equal and opposite to each other exert torque?
Yes. Since torque is F x R, even if two forces are equal and opposite they point where they are applied may lie at different distances from the axis of rotation thus resulting in a net torque.
If Two forces have the same magnitude will they produce the same amount of torque when they are applied to an object?
The two forces will produce the same torque if : R1xF1 = R2xF2; r1f1sin(R1F1) = r2f2sin(R2F2). The magnitude of the forces can be the same (f1=f2=f) but their angles with the the displacement (R) can be different, r1fsin(R1F1) = r2fsin(R2F2),and the torque will be the same. Torque is the vector product of the force and displacement.
When is net force zero but torque is not?
When multiple forces acting on an object cancel each other out, resulting in a net force of zero, but those forces are not aligned to pass through the object's center of mass, causing a torque to be present. This situation can occur when forces are exerted at different distances from the center of mass, creating a rotational effect even though the object remains stationary.
What is An example of case when resultant force is zero but torque is not zero?
A common example is a see-saw where two forces balance each other out and create a zero resultant force, but the torques produced by the forces are not equal because they act at different distances from the pivot point. This results in a non-zero net torque causing rotation.
How is science involve in freestyle skiing?
the force of torque by spining and other forces involved in a flip rotation or moguls
Is it possible for forces acting on a given body to balanced each other and still rotate due to these balanced forces?
Yes. For the object not to move, two conditions must be satisfied: (1) The vector sum of forces must be zero, and (2) The vector sum of torques must be zero. Do some reading on torque, for more information.
Does torque always result in movement?
No, torque does not always result in movement. Torque is a measure of the rotational force applied to an object, but if the object is fixed or there are opposing forces that counteract the torque, it may not rotate. Movement occurs only when the applied torque exceeds the resisting forces or constraints.
What is the restraining torque?
Restraining torque refers to the torque exerted by a mechanism or device that opposes the motion of a rotating object. It acts to prevent or limit the rotation, often as a result of friction, load, or other forces. In engineering, understanding restraining torque is crucial for designing systems like brakes, clutches, and other mechanical components to ensure stability and control.
What are non-forces?
the non fundamental forces are Tension,Torque,Elastic,Normal,Gravity,Friction.
What is resultant torque of a couple?
The resultant torque of a couple is the vector sum of the individual torques produced by the two equal and opposite forces that make up the couple. It is the product of the force magnitude and the perpendicular distance between the forces. The resultant torque of a couple is constant and does not cause linear acceleration but only rotational motion.
What is the difference between torque and moment, and how do they relate to each other in the context of physics?
Torque and moment are both terms used in physics to describe rotational forces. Torque specifically refers to the force that causes an object to rotate around an axis, while moment is a more general term that can refer to both rotational and linear forces. In the context of physics, torque is a type of moment that specifically relates to rotational motion. They are related in that torque is a specific type of moment that causes rotational motion in an object.
Why don't two forces balance each other?
Two forces may not balance each other if they are acting in different directions or have different magnitudes. When forces are not equal and opposite, they result in acceleration or movement of the object in the direction of the greater force.
