Vernier Software & Technology

# Newton's First Law

## Introduction

Everyone knows that force and motion are related. A stationary object will not begin to move unless some agent applies a force to it. But just how does the motion of an object depend on the forces acting on it? In this experiment you will begin to examine the role that forces play in motion of an object.

## Objectives

In this experiment, you will

• Collect position, velocity, and time data as a cart is launched by a spring and slowed by friction.
• Analyze the position vs. time and velocity vs. time graphs.
• Investigate the effect of varying the friction on the velocity of the cart.

## 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?
