**What is torque simple words?** 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. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.

**What is torque and SI unit?**

Unit of torque: **newton metre (N m)**

The quantity torque (or moment of force) may be thought of as the cross product of force and distance and the SI unit for torque is Newton metre, N m (m^{2} kg s^{–}^{2}).Apr 3, 2563 BE

**What type of force is torque?** In physics and mechanics, torque is the **rotational equivalent of linear force**. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study. It represents the capability of a force to produce change in the rotational motion of the body.

**Is torque a force or energy?**

If you think torque is measured in Joules, you might get confused and think it is energy, but it is not energy. **It is a rotational analogy of a force**.Sep 20, 2555 BE

## What is torque simple words? – Additional Questions

### What are the 3 units of torque?

There are three common torque units: **SI (International Standard) based on Newton meters, Metric based on kilogram force centimeters, and American/ English based on inch pounds**.

### Why torque is called moment of force?

Torque (also known as moment, or moment of force) is **the tendency of a force to cause or change the rotational motion of a body**. It is a twist or turning force on an object. Torque is calculated by multiplying force and distance. It is a vector quantity, meaning it has both a direction and a magnitude.Aug 2, 2562 BE

### What is the relationship of force and torque?

Torque is defined as **Γ=r×F=rFsin(θ)**. 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.

### Is torque and moment of force same?

**Torque is the measurement of the turning force of a body, while the moment is the measurement of the perpendicular distance from the point of rotation to the force’s line of action**.Aug 12, 2562 BE

### What is rotational force?

A rotational force, also known as a torque, **depends upon the force and where that force is applied**; torque = lever arm x force. The lever arm is the perpendicular distance from the force to the axis of rotation. A “lever arm” is also known as a “moment arm”.

### Can the torque be negative?

Oh, **torque can be positive or negative**. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise.

### What is the unit of inertia?

The unit of moment of inertia is **a composite unit of measure**. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square.

### What is the symbol of torque called?

The symbol for torque is typically **{boldsymbol {tau }} or τ**, the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.

### Is torque a scalar or vector?

Torque is **a vector quantity**. The vector representing torque points perpendicular to the plane of motion.Aug 6, 2557 BE

### Why is torque a vector?

The vector or cross product is another way to combine two vectors; it creates a vector perpendicular to both it the originals. In vector form, **torque is the cross product of the radius vector (from axis of rotation to point of application of force) and the force vector**.

### How do we calculate torque?

To calculate load torque, **multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r)**. If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.Jan 14, 2563 BE

### What does it mean when torque is zero?

What is zero torque? Zero torque is defined as “**for any object under rotational motion, if net perpendicular force is zero, then rotational equilibrium sets up and thus angular acceleration is not possible**; this condition is zero torque.”

### What is 1 Nm of torque?

One newton-metre is **the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long**.

### What is torque ratio?

A gear train can be analyzed using the principle of virtual work to show that its torque ratio, which is **the ratio of its output torque to its input torque**, is equal to the gear ratio, or speed ratio, of the gear train.

### Why is torque important?

In terms of acceleration, **torque plays a bigger role in how quickly your car accelerates**. That’s because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.Jul 20, 2564 BE

### What is torque vs speed?

**Torque relates to the rotational force of an electric motor while speed refers to the rate that the motor can rotate**. This means that torque is associated with rotational force while speed relates to the rate of rotation which can be calculated by examining the RPMs, or revolutions per minute.Nov 22, 2564 BE

### How do you increase torque?

An effective modification that will increase torque significantly is to **install a turbo or supercharger**. Forced induction forces air into your engine, increasing the power the engine provides. Depending on the torque curve you prefer, a turbocharger will need time to spool before it provides torque benefits.Jun 30, 2564 BE
