Results/Analysis/Physics
In this experiment we test Newton’s Second Law by observing the relationship between
the acceleration of objects of different mass. We test this using the equation d=1/2at
2
. In
this equation d is the distance traveled by the cart, a is the acceleration of the cart, and t is
the time that it takes the cart to travel the distance measured. This finds the acceleration
of the cart in which we can enter into Newton’s Second Law equation F=ma. This
equation states that the product of the mass of an object and its acceleration equals the
force acting on the object.
