The unit of work and energy is the Joule (J).
\text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta)
\]
where:
- Force is measured in Newtons (N),
- Distance is measured in meters (m),
- θ is the angle between the direction of force and motion.
1 \, \text{Joule} = 1 \, \text{Newton} \times 1 \, \text{meter}
\]
So, both work and energy are measured in Joules (J), where 1 Joule equals 1 Newton-meter.
- Work: It is done when a force is applied to an object, causing it to move. The formula for work is:
\text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta)
\]
where:
- Force is measured in Newtons (N),
- Distance is measured in meters (m),
- θ is the angle between the direction of force and motion.
- Energy: It is the capacity to do work. The unit for energy is the same as work because energy is required to do work. The Joule is defined as:
1 \, \text{Joule} = 1 \, \text{Newton} \times 1 \, \text{meter}
\]
So, both work and energy are measured in Joules (J), where 1 Joule equals 1 Newton-meter.
