Conversion of 1 kg.m to Joules
1 kg.m is a unit of work or energy. In order to convert 1 kg.m to Joules, we need to know the conversion factor between the two units.
The conversion factor between kg.m and Joules is given by the acceleration due to gravity, which is approximately 9.81 m/s^2. This means that 1 kg.m is equal to 9.81 Joules.
Therefore, the correct answer is option 'A' - 9.81 Joules.
Explanation:
- Heading: Understanding the Units of Work and Energy
- Bullet point: Work and energy are two closely related concepts in physics.
- Bullet point: Work is defined as the amount of energy transferred when a force acts on an object and causes it to move a certain distance.
- Bullet point: Energy is the ability to do work, and it comes in many different forms, such as kinetic energy, potential energy, and thermal energy.
- Bullet point: The SI unit of work and energy is the Joule (J).
- Bullet point: Other common units of work and energy include the calorie, the kilocalorie, and the electronvolt.
