Teacher guide featuring 15 labs designed for Advanced Placement Physics 1.

Graphical Analysis: Motion

Lab Summary

Students use a motion sensor to measure the position and velocity of a cart on a track to determine the graphical relationship between position, velocity, and acceleration versus time graphs.

Theory

How are the graphs of position versus time, velocity versus time, and acceleration versus time of an object undergoing constant acceleration related? Experimentally determine the relationships between the graphs of position, velocity, and acceleration versus time for an object undergoing constant acceleration, both positive and negative.

Method

The Structured version of this lab activity is divided into three parts: Part 1 – Students use a motion sensor to measure the position and velocity of a cart on a level track as they push the cart down the track with constant velocity. Part 2 – Students use a motion sensor to measure the position and velocity of a cart on an inclined track as they release the cart, which travels down the track with constant positive acceleration. Part 3 – Students use a motion sensor to measure the position and velocity of a cart on an inclined track as they push the cart up the track with constant negative acceleration. Based on their data from all three parts, students establish a graphical relationship between the curves of position, velocity, and acceleration versus time graphs for a cart in motion. Students are then given the shape of one of the motion graphs and using this relationship, they predict the shape of the curves of the other two graphs.
