Lab : Motion with Constant !

Acceleration

Introduction:

The purpose of this lab was to experimentally observe how an object’s position and

velocity change while it is moving with a constant acceleration. The question for this lab was

“ How does an object’s position and velocity change as the object accelerates?” The

hypothesis I created for this lab was, If the fan speed increases, then the acceleration of the

cart increases, because a greater fan speed supplies more energy to move the cart. For this lab

I used a simulation to measure the position and velocity of a cart as it accelerates along a

frictionless surface. I completed three trials using three different fan speeds to move the cart

and generate data, and then calculate the average velocity of the cart for each of the three fan

speeds. I also used this to determine the acceleration of the cart from a graph of Velocity vs.

Time. Finally, I ran one more trial in which the acceleration will be removed halfway through the

run to interpret how velocity changes.!

Procedure:

1.Open the simulation. !

•a) #Be sure to follow all the directions provided in the lab guide as

well as on screen during the $

virtual lab. !

•b) #Open the Gizmo “Force and Fan Carts” link in the virtual lab

and watch the demo by clicking the demo icon at the bottom-left

corner of the activity. !

•c) #When the demo is complete, close it and return to the

Experiment setup. !

1.Run the simulation on Low fan speed to identify changes in

position, velocity, and acceleration of the cart.

a) Select Low for the fan speed, and No Friction for the surface type. !

•b) #Open the Data tab and select the buttons Speed and Line graph. !

•c) #Click the Play button. Let the cart run past the finish line. $

Motion with Constant Acceleration Lab Report

Introduction

In this lab , I used a simulation to measure the position and velocity of a cart as it

accelerated along a gentle surface. This lab was a virtual lab, in which I calculated the average

velocity of the cart, and used velocity vs. time graphs to determine the acceleration of

the cart.

Purpose: To observe how an object's position and velocitychange while moving at a constant

acceleration.

Question: How does an object's position and velocitychange as it accelerates?

Hypothesis: If there is a greater fan speed, therewill be greater acceleration because greater

fan speed gives more power to move the cart.

Independent Variable: Fan speed

Dependent Variable: acceleration of cart

Materials I used

●Computer

Procedure

Step 1: Open the fan simulation.

Step 2: Put fan speed on low to identify any changes in position, velocity, and acceleration in

the cart.

Step 3: Put fan speed on medium to identify any changes in position, velocity, and

acceleration in the cart.

Step 4: Put fan speed on high to identify any changes in position, velocity, and acceleration in

the cart.

Step 5: Calculate the data and put it in a table.
