# Net Work - Kinetic Energy Theorem

Recommended for High School through College.

## Introduction

The *Net Work-Kinetic Energy Theorem* can be derived from Newton's Second Law. If the velocity of an object is measured, this theorem can be used to calculate the net work on an object when the force on it is not constant. In this assignment you will view a movie of a low-friction cart with a force sensor mounted on it. The cart and force sensor are being pulled with a variable force.

## Objectives

In this activity, you will

- Use the position and force data recorded by sensors to verify the theorem.

## Software for Experiment

This experiment uses Logger *Pro* software for video analysis. The video for analysis is included with the lab book.
