NORAH NALUNKUMA PHY 251 10/12/11 EXPERIMENT 5 PROJECTILE MOTION OBJECTIVE: In this lab we aim to calculate the horizontal velocity of a projectile by measuring the distance between the area an item is launched from, and the area at which this object lands. We will then predict the landing place of the same projectile if we raise its launch site by a set distance. These two factors will give us a great understanding of velocity in the
Experiment #1 Reaction Time Purpose and Preliminary Discussion: In this experiment, we tested reaction times for ourselves and various objects. For part 1, the purpose was to test our individual reaction time using a stop watch, measuring how long it would take to start and stop. Part 2 was measuring eye and hand reaction time, using a pencil and piece of paper, the object was to make as many dots as possible within 5 seconds. Part 3, again testing our own reaction time, involved dropping a meter
Physics Lab Report Lab 3: Energy and Momentum Group and name Abstract: In our experiment, we were trying to find the energy loss due to semi elastic collision and friction. Also we found the efficiency of the collision using certain equations. We found out that the loss of energy due to semi elastic collision is a lot more than the loss of friction. We had many external errors with measuring because of our inaccurate source of measuring system. The materials we used were 6 steel ball bearings
Physics Daisy Khenchanthavong Period 5 5/12/12 Lab: Sound in Strings and Tubes I. Introduction: The speed of sound is not constant, but varied. It varies through pressure, temperature, and where it is traveling through. The vibrations of kinetic energy molecules create the speed of sound, making the molecules adjacent and tightening their bonds. For example, sound waves can go through solids much easier than liquids
would plug this into the Kinematics equation described in the procedure to calculate reaction time. First of all to do this, we had to measure the final position for each member. We held the meter sticks from 100 cm side so that the final position would be relative to the 0 cm. We put X's for group members when they totally missed it and that still divided by 4 for avg final position.-this changed up our reaction time and might have been a source of error. Then we took the average of the four final
I will use examples of playing guitar, swings, electricity, automobile accident and football as every day examples of use of Physics in our life. The guitar is the most common stringed instrument, and shares many characteristics with other stringed instruments. A guitar string is a common example of a string fixed at both ends which is elastic and can vibrate. The vibrations of such a string are called standing waves, and they satisfy the relationship between wavelength and frequency that comes
Lab: 3/28/2014 Acceleration of the air hockey punk Background information Pulley system is a device that is made of grooved wheels. It is a popular tool that uses to help people to lift up heavy objects with a simple structure; rope and a wheel. The design of the pulley is base on Newton's second law( if the net force is not balance ,the object accelerates in the direction of the net force). The pulley system that was used in this
5/20/2014 Egg Drop Competition Lab Abstract: The Goal for the lab is to design and build a contraption that can protect 1 large Grade AA raw egg from breaking when it is dropped from the second floor balcony of the Pg Bldg at Citrus College. At the Day 1 we design the first contraption, and find the physics behind contraption. At the day 2, we test the prototype, and if the egg broke, we should adjust it. After the adjustment, we measure the mass, height of drop, and time in flight of the contraption
Forces and Motion Part :1 September 23, 2014 Aaron Musick Physics Lab 001 Tuesday 3:15 P.M. Introduction and Theory This lab deals with Forces and Motion, but specifically deals with the effects that Newtons laws have on Velocity (v), Acceleration (a), and Position (x). More specifically, Newton’s 2nd law, which states that Force (F) is proportional to Mass (M) multiplied by Acceleration(a)
Reaction Time Lab Problem Statement: Student A and Student B had a race to see who the faster sprinter was. After being set off by Student C it was discovered that student A won by a small amount. Student B claims that he Student A had won due to having a faster reaction time. Plan and design a lab to certify the student’s claim Hypothesis: Since x=1/2 gt2 for object falling freely the value of t can be calculated using t2= √2x/g; where g is 10m/s-2 and is gravity. Aim: To determine the
