REMARKS
On the first part of the experiment we need to get the coefficient of friction. First we put a mass
of 20 g on the block that made it weight 137 g. Then we add mass little by little as possible to the pan
until the block moves at a constant veloci

Remarks
On the first part of the experiment, we aim to get centripetal force using a constant mass and a
variable radius. We started the radius from 18.5 cm to 20.5 cm for 5 trials with 0.5 cm increment each
trial. I noticed that the higher our radii are,

Remarks
In table 1, we have 5 trials of different displacements from 50 cm to 70 cm with 5 cm
increment each value. Using the timer, we get the time of the cart travelled with respect to different
displacements. Based from the data that we gathered, I can

Remarks
During the experiment we put specific amount of loads to the three hangers at specific angles
given. Then I noticed that the ring is not in the center anymore being pulled by the three hangers at one
direction. Then we added loads to the fourth ha

Remarks
On part A of the experiment, the experiment with constant mass and changing net force, I
noticed that as we add mass in the mass of the hanger, the net force increases in computation thus
resulting for the acceleration of the cart to increase also

Remarks
On the first part of the experiment, we get the average initial velocity of 5.0706 m/s using the
vertical distance of the launcher and the horizontal distances from the five trials. Based from no error
point of view, the velocity should always be

Analysis
In the experiment we studied the simplest kind of motion; the motion of a particle in a
straight line that can be described in terms of space and time. It is said to be one dimensional.
The experiment is divided into three parts. It includes find

Analysis and Conclusion
We learned in the past experiment the motion of the object in one dimensional motion. In
this experiment, we analyzed the motion of a projectile. Projectile motion is a special case of
two-dimensional motion. We were able to explai
