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.

What factors determine the amount of work required to lift an object?

How is work calculated using force and distance?

What is the relationship between newtons and joules in the context of work?

Calculate the work done in lifting an object if 40 newtons of force is applied over a distance of 1.5 meters.

Explain why lifting a large rock requires more work than lifting a marshmallow.
