![]() ![]() (a) We analyze two-dimensional projectile motion by breaking it into. The results of this lab concur with my theory, and demonstrate that one can virtually predict the range of a projectile by using the right procedures. Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown with some initial velocity near the earth’s surface, and it moves along a curved path under the action of gravity alone. In part a the figure shows projectile motion of a ball with initial velocity of v Figure 2. There was the possible chance of air movement due to the air conditioning/heating system and people moving about the room, however this air movement is so picayune that error caused to the lab from this factor would be too minuscule to show up in my data. With kinematics, we dont have to worry about the shape of an object, its mass, or the forces that are moving it. Q: (Bonus) What term can be neglected in the equations of motion for a. We performed this lab in an indoor environment that had no influence from outside factors. Kinematics is the study of motion without considering what caused it. subjected to the loading shown, derive equations for the shear force V. ![]() rigid body rotation and equations of rotational motion, comparison of. Moreover, human error in determining the last decimal place of the measured range values and the measured Δy value, as well as the placement of the range target paper at the predicted range measurement could affect the resulting average range. I do not think wind resistance is a factor in this lab. Projectile Motion - Maximum Height, Range and Time of Flight of a Projectile. When aligning the mini launcher at 40.0° and the tape measure from the ground to the mini launcher using a plumb bob, parallax error could affect the resulting measurements due to the angle of observation. There were possible sources of error that were present in this lab. xRangeR (in other words, R, stands for Range.) The Range Equation or R v i 2sin2 (i) g can be derived from. It is the displacement in the x direction of an object whose displacement in the y direction is zero. I now want to introduce drag into this function. Deriving the Range Equation of Projectile Motion The range of an object in projectile motion means something very specific. ![]() The predicted range was in close proximity with the average range the 0.018-meter difference between the two ranges resulted in a percent difference of 7.279%. 1 Given the initial velocity v 0 and angle of a projectile on the ground, using Newton's second law and the acceleration due to gravity g 0, g, I was able to derive its position vector function: F m a m g r ( t) ( v 0 t cos, g 2 t 2 + v 0 t sin ). By splitting the 0.033-meter difference between the highest range value and the lowest range value, I discovered that the range measurement uncertainty is 0.0165 meters. Throughout this lab, I have predicted the range of a projectile using a derived equation and certain variables, such as Vo, θ, and ΔY, in order to recognize how close my theory came to the average range found. ![]()
