Lab #3A: Cart on a Ramp
Objectives:
In this lab we are using a ramp with an incline and a motion detector attached to the end of ramp. We are using a low-
friction cart to collect position, velocity, and acceleration vs. time graphs, we are collecting these graphs to analyze them
and to determine the best fit equations for these time graphs. With the graphs we are also determining the mean acceleration from the acceleration vs. time graph.
Equipment:
Station #:5
Partner: Tristan
, rating: #5/5
Computer
Logger Pro Program
LabQuest Mini
Vernier Motion Detector
Cart, track and feet
Elastic
Preliminary Questions:
#1: (Don’t have logger pro) Describe: At first, the cart is somewhere along the ramp. It is anticipated that the cart will initially move with some initial
velocity up the ramp and some first negative acceleration (down the ramp) caused by the acceleration caused by the cart's weight. The cart is supposed to keep rolling up the ram in this manner until it reaches a specific point in the ramp and time. where the cart stops traveling in the ramp and the velocity ultimately becomes zero. The cart is now anticipated to gain velocity in the opposite direction as a result of the approaching negative acceleration (it begins traveling down the ramp) and continue moving until it reaches the end of the ramp.
#2: (Don’t have logger pro)
Describe: It is anticipated that the cart will initially move with some initial velocity up the ramp and some first negative acceleration (down the ramp) caused by the acceleration caused by gravity on the cart. Up until a certain point, when the velocity eventually becomes zero and the cart stops travelling up the ramp, the cart is anticipated to continue moving in this way (rolling up the ramp). The cart is now anticipated to gain speed in the opposite direction as a result of
the approaching negative acceleration, travelling until it hits the ramp.
#3: (Don’t have logger pro)
Describe: Since the acceleration is constant, the graph will follow a horizontal line and the acceleration will remain constant throughout.
Procedure:
Part 1:
Procedure:
In this lab all we had to do for preparation was to attach the cable to the LabQuest Mini and to the computer. Everything
else was already set to go. As soon as we got everything ready to go, we just did some practice trials to see if everything
is working properly. We thought our first trial was pretty good, but we ended having to re-do it since the graph was not accurate. After another trial, we ended up getting a very good graph to being able to analyze it. Step #5:
Analysis Part 1:
#1:
Why are the graphs inverted?
It is inverted because it starts from far away and goes toward the ramp which is why the y-axis of the graph is fro 1 m to 0.2 m.

Velocity - Time Graphs
We also know that acceleration = final velocity - initial velocity

In the same way we use motion graphs to calculate velocity, we can use them to calculate acceleration.

standing still.
