# Projectile motion using photogates

Lab 4 projectile motion purpose: the purpose of this lab is to investigate the relationships among the initial velocity, time of flight and distance traveled for an object in projectile motion. Prevent accidental movement of the photogates, use tape to secure the ring stands in place connect the photogates to the digital (dig) ports of the interface note: connect the sensors documents similar to lab 1-projectile motion how reliable are animal experiments uploaded by all animal rights experimental determination of friction. Measuring the e ects of air drag using projectile motion m j milliman, d r brown, and s r krutz department of physics, wabash college, crawfordsville, in 47933 projectile motion, but it is necessary for us to have some valve, a unistrut frame, a pair of photogates, and a laser used for sighting.

In this experiment designed for use with pasco capstone software, students use a projectile launcher to better understand the kinematics and dynamics of projectile motion since measurements for these experiments involve single point measurements of time or velocity, the smart timer is the ideal timing instrument. Projectile motion 2 when the projectile reaches its maximum height, ℎ, the speed of the projectile is zero and therefore the kinetic use photogates to determine the initial speed of the ball predict and verify the time of flight of a ball launched at an angle. Using the distance between the photogates and the measured time the ball takes to travel between the gates, you can find the average velocity of the ball at the bottom of the track.

Projectile motion 5you must enter the distance, ∆s, between photogates in order for logger pro to calculate the velocity the program will divide this distance by the time interval ∆t it measures to get the velocity (v = ∆s/∆t)carefully measure the distance from the beam of photogate 1 to the. Measure the speed of hot wheels cars using photogates determine whose car is fastest and give possible explanation why it is the fastest explore the relationship between speed and mass of hot wheels cars projectile motion 19 - 2 physics with computers physics with computers 19 - 5. Experiment 4 projectile motion i objective the objective of this experiment is to study projectile motion a ball will roll down a ramp leaving the end of the ramp and becoming a projectile with a horizontal initial velocity this.

Student projectile launcher with photogates the student projectile launcher is a great tool to determine the relationship between launch angle, launch velocity and projectile range this durable launcher can fire a small projectile ball at three different speeds and vary the launch angle between -45° and 90. Phy1111l/2211l projectile motion page 23 of 27 installing the photogate bracket (me-6821) the photogate bracket is an optional accessory for mounting one or two photogates on the mini launcher to. Measure the velocity of a ball using two photogates and computer software for timing apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion take into account trial-to-trial variations in the velocity measurement when calculating the impact point.

## Projectile motion using photogates

Use photogates and a time-of-flight pad to measure the initial speed and the time of flight of a projectile use capstone to record the motion compare the time of flight for the projectile when it is launched horizontally at different initial speeds. Use photogates to determine the initial speed of the ball predict and verify the time of flight of a ball launched at an angle confirm that the initial kinetic energy of a projectile shot straight up is transformed into an equal amount of gravitational potential energy. Two dimensional motion activity projectile motion purpose a projectile launched into the air either horizontally or at an angle represents two dimensional motion using a launcher and two photogates, you will determine the initial velocity of a projectile (a 25mm steel ball) by launching the ball to the.

Summary students use a ball launcher to study projectile motion by using a lego nxt by using a lego nxt brick and light sensor to make a photogate and mindstorms software with real. Experiment: projectile motion page 1 of 5 experiment: projectile motion you have probably watched a ball roll off a table and strike the floor you will roll a ball down a ramp and determine the ball’s velocity with a pair of photogates you will use this information and your knowledge of physics to predict where the ball will land when. University of utah – department of physics & astronomy 45 physics 2015- lab 3 projectile motion room for your calculations [3 pts total] activity 2 – measuring vo directly now, like in your homework, we will want to compare our calculated values of vo with a directly determined value.

Determine the ball’s velocity with a pair of photogates you will use this information to predict where 1101/1125 projectile motion - 2 july 12, 2017 projectile motion – pre-lab 1101/1125 projectile motion - 5 july 12, 2017. When you roll a ball down a ramp, the ball is inevitably in motion this is called 'projectile motion' this lab will describe and analyze the ball's projectile motion down a ramp using concepts from two dimensional kinematics and computer software. Physics 31210 lab 2 projectile motion introduction: by rolling a steel marble down a ramp and measuring its horizontal range, you can calculate the marble's launch velocity to confirm this velocity with an independent measurement, you can use a photogate.
