Simple Machines: Calculating Work

The video tutorial explains the concept of work in physics, comparing the effort required to lift a rock versus a marshmallow. It introduces the formula for calculating work, which is the product of force and distance, measured in newtons and meters, respectively. The tutorial provides examples to illustrate how to calculate work in joules, demonstrating that lifting a heavier object requires more work than a lighter one.
