Newtons Principle

Introduction

In this lab we studied Newton’s second law (F = ma) in the dynamic case where a does not equal zero. Newton’s second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its’ mass. This was demonstrated using the Atwood machine.

The Atwood machine was used to analyze the relationship between the acceleration of the falling mass and the net force acting on the system.
