As a former Industrial Ph.D. Physicist, Force Sensor at this price point is delightfully ranch-friendly and perfect for homeschooling. The gauge comes in a well-designed shadow box with end accessories for visualizing and measuring push/pull solutions. I use it to visualize and quantify a minimal but reasonable solution to mechanical advantage through levers, ropes, guide arms, structure, weight suspension, balance, etc. Newton is read directly from the sensor. The language of mass, force, and acceleration is expressed in algebraic variations of F=ma...along with standard gravity @32'/sec^2, F=ma is one of my all-time favorite equations in life experience. The cattle on the ranch show a mechanical advantage over me almost every day. I have to be one step ahead of the cattle. A proven practical understanding of force, mass and acceleration is essential for immediate decisions and future activities. While the meaning may have been forgotten, Newton's language is sure to permeate science. The Mxmoonfree NK-500N push-pull force gauge brings everything back into focus. Was my review helpful?
