# Newton's Second Law

## Introduction

In your discussion of Newton’s first law, you learned that when the sum of the forces acting on an object is zero, its velocity does not change. However, when a net force acts on the object, it accelerates. In this experiment, you will determine the relationship between the net force acting on an object and its acceleration.

## Objectives

In this experiment, you will

• Identify the forces acting on an object both when its change in velocity, Δv, is zero and when it is accelerating.
• Collect force, velocity, and time data as a cart is accelerated on a track.
• Use graphical methods to determine the acceleration of the cart.
• Determine the relationship between the cart’s acceleration and the net force applied to it.
• Determine the effect of the mass on the relationship between acceleration and force.

## Sensors and Equipment

This experiment features the following Vernier sensors and equipment.

You may also need an interface and software for data collection. What do I need for data collection?
