## What are the different units of work?

The SI unit of work is joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter….SI Unit of Work.

SI unit N.m Joule
CGS unit dyne-cm Erg
Dimensional formula ML2T-2

### What are 3 examples for units for time?

The most common units are the second, defined in terms of an atomic process; the day, an integral multiple of seconds; and the year, usually 365 days. The other units used are multiples or divisions of these three.

What is work and its types?

Work is a scalar quantity and is the product of two vector quantities. Depending on the value of q, there are three types of work: When q = 0°, work is said to be positive. Stretching of the spring is an example of positive work as the force is acting in the direction of displacement of the spring.

What is the unit of work done class 9?

joule
The unit of Work is Newton metre (Nm) or joule (J). 1 Joule is defined as the amount of work done by force of 1 N when displacement is 1 m. when both the force and the displacement are in the same direction, positive work is done.

## What is current unit?

Unit of electric current: ampere (A) The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.

### What are the basic units of time?

The base unit for time is the second (the other SI units are: metre for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance).

What is work write its unit?

Work is force applied over distance. The standard unit of work is the joule (J), equivalent to a newton – meter (N · m). This reduces to one kilogram-meter squared per second squared (kg · m 2 /s 2 or kg · m 2 · s -2 ) in base International System of Units (SI) units.

What are the absolute units of work?

Absolute units: (i) SI System – Joule is the unit of work in SI system. Work done is said to be 1 J if a force of IN displaces the body by 1m in the direction of force applied.

## What is work write the unit of work?

In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work.

### What is the meaning of 1 unit?

It is basically measurement unit of electrical energy consumption in Joule. 1 kWh (kilo watt hour) and 1 Unit are same. 1 kWh is the amount of energy consumption by 1 kW load in one hour. Therefore, 1 Unit = 1 kWh.

Is system a unit?

The International System of Units is a system of measurement based on 7 base units: the metre (length), kilogram (mass), second (time), ampere (electric current), Kelvin (temperature), mole (quantity), and candela (brightness)….Derived units.
