Pre-Lab Questions
1. What is the acceleration of a ball that is vertically tossed up when it reaches its maximum
height?
The speed of acceleration of the ball is -9.8 m/s 2, at any elevated place as gravity is always
constant in the downward direction.
2. Describe what the slopes of a position vs. time graph mean in relation to velocity.
The steeper then the slope the higher the velocity and the more shallow than the slope then the
less the velocity
3. State the 1D and 2D kinematics equations you will use in this lab in variable form. (Do not state
equations that you will not use.)
Displacement: s=ut+(1/2)at 2
Final velocity: v=ut+at
Final velocity squared: v 2 =u 2 +2as.
4. Why is it important to consider the X and Y components of the kinematics equations
independently?
Since, in the two dimensional motions, X and Y components are not related, the movement in
one will be different to the movement in the other, which is perpendicular to each other.

EXPERIMENT 1: FREE FALL CALCULATIONS
Introduction Questions
1. This experiment contains two separate tasks: one where you will drop two strings with hex nuts
tied at varying intervals, and another where you will drop a single hex nut from a specific height.
In your own words, explain the steps you will take in preparing the ropes for the first task. Your
lab will not be graded without a detailed explanation that reflects your understanding of the
preparation for this experiment.
I shall begin by determining the length of my string which will be 2.5m long and then cutting it.
Then I shall separate the hex nuts with a distance of 40 cm and then tie each nut on the string in
order not to move with each other until you reach the end of the string. I will also ensure that I
note that some extra string might be left. And finally over the pan I will be holding the string to
ensure that the hex nuts are not in motion. At this point, I am prepared to start with the tests
2. What measurements will you be required to take during this experiment?
I will experiment by measuring the fall height then record the time each of the hex nuts takes
during three attempts. I will also use the measurement of spacing between the hex nuts.
3. If you drop a ball, and then one second later drop a ball identical in mass, size and shape, what
happens to the distance between them as they fall? The answer to this question is integral to
understanding the rest of the lab, so ensure you have a full understanding of it before
answering.
Due to constant acceleration, the resulting distance will be in increase between the two balls as
the balls keep falling. These two balls will have the same acceleration of the balls alongside the
time in spite of any differences brought by their masses but the second ball will remain slower
than the first ball as it is dropped later. When the first ball drops, the distance will be increasing
at a constant rate due to force of gravity multiplied with the difference between time which is
one second. After one second the difference between the two will be approximately 9.8 meters.
4. How do you think Question 3, above, pertains to this experiment?
It demonstrates the issue of separation under a constant acceleration as a result of gravity and
the need to separate as time goes. This is one way through which one can understand the
changing clanging noise as the nuts fall.
5. From what height will you drop the single hex nut?
0.76m.
6. Using the kinematics equations, calculate the length of time it will take the single hex nut to
land, given the height that you provided. You must show the specified portions of the
calculation:
, Lab 2 Kinematics PHY250L
a. State the kinematics equation you will use in variable form. It must be legible and have
the proper formatting.
D=1/2gt^2
b. Solve the above equation for the time variable. Your equation must have proper
formatting and should be in variable format.
t² = 2d/g
t = √(2d/g)
c. Solve for the predicted time it will take for the hex nut to reach the ground.
t = √(2 × 0.76m / 9.8m/s²) = 0.39s
Data and Observations
In the table below, input your observations of the time it took for the hex nut to fall from the height you
specified in the previous section.

Trial Drop Height (m) Time (s)

1. Clearly describe the pattern of noise generated by the equally spaced hex nut pattern.
Specifically, was the pattern consistent, or did it change as the rope descended?
The hex nuts were evenly spaced following a certain arrangement. The sound produced was
rhythmic in progression; the greater the velocity became the less were the periods of the
clanging of the nuts falling.
2. Clearly describe the pattern of noise generated by the unequally spaced hex nut pattern.
Specifically, was the pattern consistent, or did it change as the rope descended?
The irregularly spaced nuts produced a reverse acoustic. The clanging periods became more
uniform \ as the rope fell, again because the nuts were kept farther apart at the top to allow the
