In this experiment, the data analysis proves that the amount of time required for the body launched into motion is the same regardless of the initial velocity or range of the projection. This is because the ball is acted upon by acceleration due to gravity; hence the downward acceleration causes the ball to fall to floor over the same period of time non-regardless of the initial velocity. The slope of the graph represents the time taken for the ball to reach the ground after it is launched from the ramp, and its unit is (s) seconds. The ‘motion implies an attached force’ concept is wrong. The concept that should be considered instead is that of momentum. The Newton law related to the concept is Newton’s second law, i.e. F=ma. Newton’s second law of Motion states that the total of all forces acting on a body is equal to the product of its mass and acceleration. This law applies to projectile motion in the sense that projectile motion is the sum of two or more forces that follow the path of the trajectory. Errors during this experiment include, error in determining the beginning of the range on the floor using the plumb line. This is classified as a random intrinsic error. There was also an error in trying to accurately determine the value of the diameter of the ball using the vernier caliper. This is classified as a random error of measurement. There was also a measurement error incurred when measuring the values of the different ranges with the meter rule from the paper strip.

Conclusion The time taken for the ball to reach the ground is the same non-respective of the initial velocity with which it leaves the ramp. The purpose of the experiment was to fully understand the principle of projectile motion. The experiment was a success as the results were within limits of experimental error.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
