Hello, readers welcome to the new post. We will discuss Difference between power and torque. Power discusses the rate of work done and torque is energy that is given when an object rotates about an axis.
In this post, we will discuss different paramerts to learn the basic differences between these two terms. So let’s get started Difference between power and torque.
Difference between power and torque
What is Power
- Energy is converted and transferred in unit time called power. The unit of power is a watt which is one-joule work done in one second
- It is also called activity performed and scalar quantity.
- Power can be related to other paramerts such as power used for movement of the vehicle on road is multiple of traction forces and velocity.
- The equation of power is
- P= ∆E/ ∆t
- P is power ∆E is energy variation ∆t change in time
- SI unit of power is a watt
- Power is generated through a generator and battery
- There are 2 main types of power electrical and mechanical power
- One horsepower is equal to 746 watts
- here are three types of electrical system power apparent real and reactive power.
- The apparent power is multiple of RMS volts and current and also called idle power
- Active power is called real power used in the circuitry denoted as P. Active power is used in resistive circuits.
- Power used in circuitry reactance is called reactive power. Denoted with Q and the unit is MVR
What is Torque
- Torque is a rotation correspondent of linear force. It is also named a moment of force, rotation force, and turning effect.
- It denotes the ability of the force to generate variation in the rotational motion of objects.
- Torque is explained as multiple of the magnitude of the force and the perpendicular distance of linear applications of force through rotation of the axis.
- The formula of torque is
- Torque = FOrce x distance
- It is a vector quantity and the unit is NM
- Torque meter used for torque value
Power vs Torque
- Torque is the capacity to do work and power is the rate of work completion in a given time. The basic use of torque is to accelerate the car in the starting phase of motion and horsepower defines the rate of acceleration of the vehicle.
- Torque is a vector quantity and power is a scalar quantity
- SI unit of torque is Newton meter and power is watt.
- Torque is measured with an equation τ=Frsin(θ) and power is measured with P=ΔEΔt
- Torque is measured with a torque meter or torque sensor. Power is measured with the use of an energy meter and multimeter.
Is it better to have more power or torque?
- If there is a need to get high speed about 140mph, then horsepower will be best. if needed to have a strong car that can pull boulders and take off fast, high torque can be important. Torque makes us quick and horsepower fast.
What is torque and power in a car?
- Torque is measuring of work of engine can perform. Horsepower defines how fast a car can complete work and that translates into the crankshaft’s turning speed. Such as buses and trucks need high torque but do not use high horsepower.
How to calculate torque?
- The torque equation is T = F * r * sin(theta), and the unit is Newton-meters. So when the sum of all torques working on an object is zero it is rotational equilibrium. Torque working on a single object cancels each other when they come with equal magnitudes and opposite directions.
What is the main use of torque?
- Torque is the rotational force generated by an engine that helps the car to move. It is good for acceleration, towing, and overcoming resistance. High torque helps to get good performance.
What is the relationship between torque and power?
- The body performing rotational motion faces torque. Torque is equal to force x radius. Hence, Power = torque x angular velocity
Is torque a speed?
- It is good to know that torque is not speed and related to the power of motors in the form of rotational forces. If there is a need for a high motor speed use a motor with high speed and for rotational force use a motor that increases motor torque.
That is all about the difference between power and torque. All details have been explained if you have any further query ask in the comments. Thanks for reading have a good day see you in next post.
