Welcome to the world of Newton’s Second Law, where we’ll unveil the secrets of how forces and objects interact. Hold on to your hats, because things are about to get a bit “force”-ful, but we promise, it’s not rocket science… well, maybe just a little!
Formula for Calculating Newton’s Second Law:
Force (F) = Mass (m) × Acceleration (a)Table of Contents
