What is torque in Physics?

torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied. Torque is measured in newton metres in SI units.

What is torque in physics class 12?

Torque is defined as the moment of the externally applied force about a point or axis of rotation. The expression for torque is, τ → = r → × F → .

What is torque Ncert?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Hence, torque can be defined as the rotational equivalent of linear force. The point where the object rotates is called the axis of rotation.

What are the application of torque?

Applications of Torque Seesaws and Wrenches. Gyroscopes. A pendulum or a parachute is applying torque when swinging. A person riding a bicycle.

Why torque is important in our life?

Torque is an important concept of physics that helps us understand how things happen around us. With the help of torque, it can be determined what the direction and magnitude of a rotational force applied on an object is, allowing you to assess the results it may generate.

What is torque and why is it important?

Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. The force is measured in pounds (lb) per foot (ft) of rotation around one point.

Why is torque important in physics?

Torque is a measure of how much a force acting on an object causes that object to rotate. In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.

What is torque in real life?

Torque is the application of force where there is rotational motion. The most obvious example of torque in action is the operation of a crescent wrench loosening a lug nut, and a close second is a playground seesaw.

How to calculate torque force?

Start with determining the force acting on the object. Let’s assume that F = 120 N .

Decide on the lever arm length. In our example, r = 0.5 m .

Choose the angle between the force vector and lever arm. If it is not equal to the default 90°, open the advanced mode of the calculator to

Enter these values into our torque calculator. It uses the torque equation: τ = r*F*sinΘ = 0.5*120*sin(90°) = 60 Nm .

The torque calculator can also work in reverse, finding the force or lever arm if torque is given.

What is the definition of torque in physics?

Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically torque can be written as T = F * r * sin(theta), and it has units of Newton-meters.

What is an intuitive explanation of torque?

Torque is similar to linear forces, but where linear forces cause an object to move in a straight line, torque causes objects to rotate. If you’ve ever opened a door, you have an intuitive understanding of torque. When you are opening a door, you exert a force on the side of the door farthest from the hinge.

How is torque related to force?

Torque is related with force which in turn is related to mass. Since weight is also related with mass, and both relations are directly proportional so we can say that a body with a greater weight will have a greater Torque produced in it.
