Next, using the equations the total distance the ball would travel was found. After that, the students called over Mr. Neenan so that he could observe the firing of the projectile launcher. The projectile launcher was at the end of the table and the calculated distance was marked off on the floor by a target. The projectile launcher was then set up perfectly horizontal and fired. Part Two: This part of the lab was to hit Mr. Bill with the projectile as he was sitting on the floor.
It is similar to hand and finger injury in its causes: the repetitive motions and the high speed of golf swing. In the articleClinical: Overuse sport injuries to the wrist, it lists two common wrist
This is done by using the conservation of momentum formula M_1 V_1=M_2 V_2 The mass of the club ×the velocity 〖ms〗^(-1) of the club or swing speed=The mass of the golf ball ×the velocity of the golf ball This has to be rearranged as we are trying to find the V_2the velocity of the golf ball after the contact with the driver, so our new equation is: (M_1 V_(1 ))/M_2 =V_2. The average driver club swing speed is 41.75354 ms-1 and the average mass of the driver is 200g this gives us values for M_1 〖and V〗_(1 ). The mass of an average golf ball is 46g this represents M_2 now we substitute our values into the equation to get the final velocity V_2. (M_1 V_(1 ))/M_2 =V_2 → (200g
Company Todd Kutta and Scott Lambrecht were both friends as well as golf lovers. During play they both were facing identical issue of determining club selection and distance. In its simplest form, the GolfLogix product consisted of a customized, handheld GPS receiver, called an "xCaddie," that indicated the distance to the green to which a golfer was hitting. A golfer could record the exact location of his ball at the beginning and end of every shot as well as the club used to make that shot. The GPS receiver employed by GolfLogix was manufactured by Garmin International, a leading maker of GPS receivers for consumer and commercial use in the United States with over $350 million in sales.
Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor. For the second and third experiments the gun fired the steel ball into a pendulum. To measure the velocity of the steel ball, when it was launched freely, carbon paper and a 2-meter ruler were used to determine the distance it travelled and then kinematics were used to calculate the balls initial velocity. When the steel ball was launched into the pendulum the laws of conservation of energy and momentum were utilized to determine the balls initial velocity. Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically.
IBDP Physics Practice Lab - Factors Affecting the Drop Time of a Falling Body By Clevis Tam Aim: To investigate how the relationship of the terminal velocity of a falling parachute depends on the mass of the clay. Variables: • Independent Variables: The mass of the Clay (g) • Dependent Variables: The time the clay takes to reach the ground (s), The speed of the clay that is processed after collecting data (ms -1) • Controlled Variables: Method of releasing the clay, the area of the parachute Materials / Apparatus: 1. Meter Ruler (0-1m, measures to 0.001m) 2. Electronic Stopwatch (measures to 0.01s) 3. Drop Height (2.56m) 4.
Lab 7: “Newton’s Second Law” Newton’s Second Law Purpose: To find the graphical and mathematical relationship between the Net forces applied to an object, its mass and acceleration. Variables: Independent: -Hanging mass Dependent: -Acceleration -Force pulling on cart Materials: * * Dynamic Cart with pegs * Force Sensor * Motion Detector * Computer with Logger Pro * Lab Pro * Ramp with Pulley * Mass Sets * String Procedure: 1. Assemble the Ramp and pulley system as shown. Attach proper length of String to the Force Sensor, and add a loop at the opposite end for attachment of various weights. 2.
As you approach the ground you will want to maintain a good prepare to land attitude with you feet and knees together, the next thing to do is land, not always the most graceful thing, but any jump you walk away from is a fantastic jump. Pre jump is the most crucial part of the jump. It’s the last time you will be able to practice everything that will take place in the airplane, as well as in the air. It’s your last chance to practice parachute landing falls or “PLF’s” as well as check all of your equipment. As the saying goes “You rigged it, you ride it.” So checking your equipment is a definite must.
Lastly we will explore standing waves and how string oscillations become affected by the string mass density. Theory As stated in order above, our first experiment of simple harmonic motion using an oscillating spring setup. By using a mass hanger attached to a rotary motion sensor, we are able to produce graphs and data to attempt to show the proofs for the theories and equations listed in the theory and graph section of the lab. The experiment started with adding 200g and progressively moved up to 350g for five trials. We then collected the data and analyzed the sine graph and the different portions of it and what they meant including the parameters and taking proper data.
HYPOTHESIS My hypothesis is that the stem of each plant will be attracted to the magnet. I think that the magnet will pull the plant's root causing it to grow away from the magnet. I base my hypothesis on my research that states that plants have different kinds of tropisms that attract to different things and cause the plant’s roots to grow downward. I also based it on the fact that magnets attract to some things and repel to other things. EXPERIMENT DESIGN The constants in this study are: How much water the plant receives How much soil is in the pot How much light the plant receives What the growing temperature is When the seed is planted How many seeds are planted in each pot Where each seed is planted How deep each seed is planted How big the pot is How far from the light the pot is The temperature of the water What time the light is turned off and on The manipulated variable is whether a magnet is being used and where the magnet is placed.
