Projectile Motion Lab Report

Objectives:

This laboratory experiment presents the opportunity to study motion in two dimensions, projectile motion, which can be described as accelerated motion in the vertical direction and uniform motion in the horizontal direction.

Procedures and Apparatus:

|Rubber Ball |White sheets of papers |
|Metal Track |Water |
|Books |Table |
|Meter-stick |Stopwatch |

• Obtain all the apparatus and material needed to proceed with experiment • Set up a ramp using the metal track and a bunch of books at any angle so that the ball will roll off. • Measure the distance from the edge of the table to the end of the ramp. • Roll the ball down the ramp and off the table but make sure to catch the ball as soon as it leaves the table; do this part 10 times and record the times • Calculate average velocity for this step

• Measure the height (vertical distance or the y-axis) of the table. • Using this height, derive t (time) from the uniform accelerated motion in order to obtain the predicted distance x. • The next step is to release the ball from the ramp and let it fall off the table to the floor. • Measure the spot on the floor where the ball hits the floor point when the ball rolls off the table. • We positioned a piece of paper on the floor on which the ball marks the spots it hit first; to achieve this we wet the ball with water so the mark will be more evident • Record these distances at least 3 times in and add them up to obtain the actual distance x. • Compare these actual results with the predicted distance, which you obtain in the first part using uniform motion.

Summary of Theory:

Projectile motion in two dimensions can be predicted by treating the motion as two independent motions; the horizontal (x) component of the...
