Results and Discussion
The experiment aim ed to verify if the Newton ‘s Second Law of Motion is true and accurate. First a series of trials
stating that a mass of the cart stayed constant meaning no set of weights were added while the force is changing by adding
more weig hts on the weight hanger. Then students perf ormed part two in which the force of the cart stayed constant
meaning there is no added weight on the weight hanger while the mass of the cart is changing by adding more weight on
it. In the t hree sets of trials performed, below is the graph to see the accuracy of the data being experimented.

Graph 1 . Constant Mass, Changing Net Force
This graph illustrates the direct proportionality of the force acting on the object to its acceleration provided that the mass
is constant which produced an equation of y = 2.1445x + 0.0534 .

Graph 2. Constant Net Force, Changing Mass
This graph illustrates the inverse proportionality of the acceleration and the mass p rovided that the net force is constant
which produce an equation of y = -1.9137x + 2.81.

After a series of trials in the experiment , the students observed the application of Newton ‘s Second Law of Motion.
Students utilized a cart on a dynamic track, a weight hanger , photogates and a smart timer to record the change in motion
of the dynamic cart. The researchers concluded that the acceleration is direct ly proportional to the force acting on the
object provided that the mass is constant but inverse ly proportional to its mass provided that the net force is constant.
The percent differences were conducted, but some e rror may have been occurred from the uneven and frictional force of
the dynamic track in the horizontal direction. The main principle of this experiment is applied to the motion of people in
everyday lives such as hitting, throwing or kicking a ball wherei n a certain distance and force is vital. Without applying
any force, an obje ct will remain at rest therefore it will not accelerate.
