## Whats bigger kJ or J?

Joules and KiloJoules are units of the international system of units (SI) that measure energy. … 1 J equals precisely 0.001 KJ, therefore there are 1,000 Joules in a KiloJoule.

## What is the formula of kJ?

kJ (Metric), energy

The joule has base units of kg·m²/s² = N·m. The base unit conversion can be remembered using the equation E = mc2, where E is in joules, m is in kilograms, and c is the speed of light in meters per second.

## What is a kJ equal to?

The kilojoule (kJ) is equal to one thousand (103) joules.

## How do you find the joules?

In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.

## What is J in Chem?

J (J): (1) The joule. An International System of Units energy unit equal to an applied force of one newton through a distance of one meter, or the energy equivalent to passing an electric current of one ampere through a resistance of one ohm for one second.

## How many Newtons are in a joule?

one newton
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

## How do you calculate joules in water?

Example: If 10 kilograms of water are heated from 10 degrees Celsius to 50 degrees Celsius, how much energy (in joules) did they absorb? Answer: The specific heat capacity of water is (roughly) 4.184 kilojoules / kg K. (10 kg) × (40 degrees Celsius temperature change) × (4.184 kJ / kg K) = 1673.6 kilojoules.

## How many joules does it take to move a car?

Travelling at 100 kilometres per hour, it has approximately 770,000 joules of kinetic energy. If this vehicle collided with a concrete wall, it would deform, transferring some of its kinetic energy into the concrete molecules. Depending on the relative mass and anchorage of the wall, this may cause it to shift.

## How do you find Newtons from Joules?

If you need to convert any number from joules to newtons, all you have to do is multiply it by 1. For example, 3.2 joules in newton meters is: 3.2 × 1 = 3.2 Nm .

## What is 1000 joules in Newtons?
