6/26/2023 0 Comments Projectile motion labtime of flight horizontal distance travelled maximum vertical height attained. This will be accomplished by determining the relationship between the launch angle and the following three kinematics variables. Purpose The purpose of this lab is to enhance your understanding of projectile motion. Reproduction for any other purpose, without the express written consent of the author, is prohibited.I.

A general conclusion about your data, based on your observations and data, and including remarks on errors based on your velocity vector determinations.įollow the instructions at the Moodle to post your lab reports where your fellow students can find them.Do you expect V to be the same in all cases? Explain your reasons.You should now be able to determine the linear velocity v = ( v x ) 2 + ( v y ) 2 The vertical velocity downwards when it hits the ground, V y = downward accelertion * time, is equal to the initial vertical velocity upwards.Īssuming no interference from wind resistance, you can double this for the total time the ball was in the air, and arrive at horizontal velocity: v y = a y t v x = h 2 t Height reached, together with the gravitational acceleration constant will allow you to determine how long your ball was falling: Determine the angle at which you achieved maximum range.Determine the angle at which you achieved maximum height. ![]() Record the angle of your platform at each trial.Make multiple launches, extending your rubber band the same distance for each launch (so that the initial force is the same).Use a setup similar to that in the diagram below.You may try videotaping the launch path to make identifying the maximum point easier. Possibilities include putting a graph or scale in place and observing the launch path against this background. Observation set 2: Experimentally determine angle necessary to achieve the maximum height and range for a projectile.įor this one, you may need to be creative in determining maximum height. Does the horizontal distance your launched ball travels make any difference?.Repeat your "experimental" several times and record your observations. ![]() Marbles hitting a hardwood floor make sufficient noise to tell whether the balls hit the ground at the same time. Have your observer note when the balls hit the ground.Practice so that you can launch and drop at the same time.Make sure the ball to be dropped can fall freely.Use the setup in the diagram below, or assemble something similar.Observation set 1: Experimentally (by observation) determine whether either ball (dropped vs. If you are launching inside the house, a freely suspended towel or blanket at the end of your target area will "catch" your projectile if you shoot too hard. Be sure that anything within range which might be damaged (Ming china, antique furniture, siblings) has been removed. A piece of thick cardboard with pushpins can be used if you don't have any other "Y" or "U" shaped frame.ĪIM YOUR LAUNCHER CAREFULLY. Launcher (sling shot or other frame which will allow you to stretch the rubber band for slinging your ammo.uh, projectiles). ![]()
