Purpose (written in past tense)
Sample of quick introduction (change me)
As you can see in figure 1, the forces affecting the motion are weight and air resistance.
Based on quick observation was noticed that coffee filter moves at constant speed
Forces include gravity, friction, and applied force. Force causes changes in the
speed or direction of motion. There are four main types of contact forces.(World
Atlas, 2022) The first one, the normal force is when nothing is happening. A book may
be sitting on a table and gravity is pulling it to the ground, but there is the table
underneath it, preventing that from happening. Applied force, is the force that is
applied to move that same book from one position to another. Tension is when two
pulling forces, directly opposite of each other stretch an object (World Atlas, 2022).
Imagine you and your sibling pulling on the book, fighting over it, stretching its covers
and pages until it pulls apart. The final type of contact force is called spring force, and
this is the force that is created by a compressed, stretched spring on any object that is
directly attached to it (World Atlas, 2022).
All motion depends on an object changing position over a period of time. There are
numerous quantities that can affect the motion of an object in this lab.
Fig. 1 Data was collected using video tracker
and a video with 240 fps.

Testable Question & Hypothesis
Testable question: How does position depend on time for a coffee filter with constant mass and
shape falling through air near earth’s surface?
Hypothesis: The coffee filter will reach terminal velocity almost immediately since it has a very small mass
and an aerodynamic shape that will be increase the drag force at the very instant it moves. Therefore, the
vertical position of the coffee filter falling through air will increase linearly proportional with time. The position
time graph will yield a linear relationship.

Type of error
Solution/Reduction of Effect
Tracking the same point on the ball
This error is due to the irregular shape of the ball and its size.
Repeat measurements to increase number of trials
Track a point at the lowest edge to be consistent
Zoom in to be able to get the same point over each measurement
The image of the 3.0 m marker is not
sharp. It is used to calibrate the
Zoom in to account for the gap between edges and the posts.
Sample of a conclusion
In projectile motion, the hypothesis stated that the motion of the object in the horizontal direction is constant velocity motion
and in the y direction it is acceleration motion because in the horizontal direction there is no force acting on the
object, whereas in the y direction there is a gravitational force acting on it. Therefore, in the x direction we don’t
have acceleration and in the y direction we have acceleration.
According to the data (table 1) and the graph (figure 2) that was obtained, we have a linear relationship (x=4.556t+0.492) between the x
position and time, which indicated that we have a constant velocity motion in the x direction. Whereas, for the
second graph, we got a second order relationship (y=-5.0537t^2 + 5.7317t + 2.5043) which indicated that the motion
in the vertical direction is acceleration motion. The results are consistent with our hypothesis.
The acceleration we got from this experiment is a=10.1 m/s^2 meaning it is greater than what we expected. The errors
made are equivalent to 3%. The results that we obtained verified our hypothesis.
A study of the positions (horizontal and vertical) of a basketball could be performed similar to a canon. In both
apparatuses, the horizontal position has a constant velocity and the vertical component is affected by gravity.
