Its Not the second law but the third law which says 'for every action there is an opposite and equal reaction.' Torque reaction is observed in helicopters motion. As the main motor rotates (that is the wings on the top), the helicopter itself tries to rotate(the opposite direction) in order to give an equal and opposite reaction. For this reason, a tail rotor ( a motor) is kept in the vertical direction towards the end of the copter so that it balances the torque produced by the helicopter ( which not to forget, was produced in order to satisfy newtons third law )

What are units of torque?
Newton-Meters
What is the difference between torque and couple?
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
What Newton Law of Motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force in the same direction as the net force?
Newton's second law of motion states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object.
Why is torque potential energy and why?
The way I understand it, torque is unrelated to energy, despite the fact that torque and energy happen to have the same dimensions, namely force x distance (in units: newton x meters). In other words, torque is not an energy; it is a different kind of measurement.
How newton's second law of motiondefines newton's first law of motion?
Newton's second law states that Force = mass * acceleration. That is, if a body is experiencing 0 net force, then its acceleration, or the rate of change of its velocity, is also 0. Newton's first law states that a body experiencing no net force will remain at the same velocity. In other words, its acceleration is 0. These are the same statement, thus Newton's second law implies the first.
Is the action force always greater than the reaction force?
No, they are always the same. That is what Newton's third law states.
What is Newton's law action reaction?
For every actions there is an equal and opposite reaction. For example, if i punch a wall i am exerting a force on the wall, but at the same time the wall is exerting the same amount of force on my fist.
What is newton's law of action-reaction?
For every actions there is an equal and opposite reaction. For example, if i punch a wall i am exerting a force on the wall, but at the same time the wall is exerting the same amount of force on my fist.
What is 1 newton meter?
1 newton x 1 meter can be one of the following:A) A joule, the unit of energy and of work.B) The unit of torque. In this case, it is written newton-meter; there is no special name for it. This use is completely unrelated to the unit of energy, even though it happens to use the product of the same units.1 newton x 1 meter can be one of the following:A) A joule, the unit of energy and of work.B) The unit of torque.

What is a newton in physics?
A "newton" is a unit of force. Other units of force are pound, ton, and dyne. (Not kilogram.)When you push on 1 kilogram of mass with 1 newton of force, the kilogram acceleratesat the rate of (1 more meter per second) per second.1 pound of force is about the same as 4.45 newtons.1 newton is about the same as 3.6 ounces of force.
How can you learn more about Torque - physics?
You can read the Wikipedia article on torque, look for other online articles about torque, or read a physics school book - look for the chapters about rotational movement. It is important that you first understand the physics of linear motion - especially Newton's laws of motion, since this is very similar, and physics books will most likely use linear motion as an analogy. Briefly, the rotational equivalent of Newton's second law (F=ma) is: (torque) = (moment of inertia) x (angular acceleration) Torque is expressed in newton-meters, and it is the product of a force, times the distance from the axis of rotation (times an angle function, if the two are not at right angles). For example, less force at a greater distance, from the axis of rotation, can have the same effect.
What is the s.i of torque?
Joule , the energy unit is the unit for Torque. Torque is vector energy.AnswerThe SI unit for torque is the newton metre(N.m). This should not be confused with the joule (which is a special name for a newton metre), the SI unit for work.With torque, the force (in newtons) acts at right angles to a radius (in metres) to produce a turning moment. With work, the force (in newtons) acts in the same direction as distance travelled (in metres).To calculate the work done by a given torque, it's necessary to multiply the force by the circumference through which the force acts.
