ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system.

The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration, force, and percent...

How to write a lab report Let’s take as an example a free-fall experiment. You drop a small steel ball from various heights and use an electronic timer to measure how long it takes the ball to hit the ground. From this you calculate the final speed of the ball using v = 2x/t. You believe that the ball will have a constant acceleration of “g,” 9.8 m/s2. This will be seen if you graph velocity vs. time and get a straight line with a slope of 9.8. You end up with a table of data giving distances...
