Questions & Step-by-Step Solutions
The unit of work is defined as one joule. What is one joule equivalent to? (2023)
Step 1: Understand that work is done when a force moves an object.
Step 2: Know that the unit of force is the newton (N).
Step 3: Know that the distance moved by the object is measured in meters (m).
Step 4: Realize that work (in joules) is calculated by multiplying force (in newtons) by distance (in meters).
Step 5: Therefore, one joule is equal to one newton of force applied over a distance of one meter.
Unit of Work – Work is defined as the product of force and distance, and one joule is the work done when a force of one newton moves an object one meter in the direction of the force.
Joule and Newton Meter – A joule is equivalent to one newton meter, which illustrates the relationship between force (newton) and distance (meter) in the context of work.
