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.
The projectile was launched three times and an average velocity was found. Part One: This part of the lab was to accurately predict how far the projectile launcher would launch the projectile when it is fired perfectly horizontally off a table. The distance from the ground to how high the ball would be fired from was measured. Then, the equations were used to solve for the time that it would take from the time the ball was being fired to when it hit the ground. Next, using the equations the total distance the ball would travel was found.
Definition- Refers to the amount of force a muscle can produce with a single maximal effort. Size of muscle cells and the ability of nerves to activate them are related to muscle strength. Test- Chin ups test, doing certain amounts of chin ups in 1 minute’s time. This test shows how much chin ups are sportiest capable of doing. Compare against Public Service test- Public services have common strength test, which tests the same muscle group, which is upper muscles.
There are thirteen points on how to shoot a basketball, but I can sum it up for you all in about eight easy steps. Step number one is foot placement. The foot under your shooting hand should be about one half foot length forward rather than parallel with the other foot. It should be in this position when shooting a set shot or before jumping for a jump shot. The second step is your body balance.
Lab 8: Ballistic Pendulum Objective: In this lab we used three methods to measure the initial velocity of a projectile from a spring gun. In the first experiment we used kinematics alone to determine the mean initial velocity for the projectile. In the second experiment we added a simple ballistic pendulum to derive the velocity of the projectile using the principles of conservation of momentum and energy. In the third experiment we used a physical pendulum, the equations for conservation of angular momentum and energy, and the equation for the period to determine the initial velocity of the projectile. 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.
Megan Lankford 10/11/12 Physics Lab: The Ballistics Pendulum and Projectile Motion Introduction/Objective In this lab, our focus was to identify the initial velocity of a metal ball by firing it as a projectile and compare it with the velocity. Also, we had to determine the initial velocity of the ball fired into the ballistics pendulum and its relativity to the initial velocity in which the ball plus pendulum moves after firing. This lab demonstrates the principle of conservation of momentum and projectile motion and how they are relative to each other. Procedure 1 To being our experiment, we had to weigh the metal ball and pendulum to give us our mass and help us determine the before and after effects of the collision. After we had taken all of our measurements we had to decide which setting we were going to fire the ball at.
Theory Overview In theory, y=yo-1/2gt^2, where y equals height in the vertical direction.Time, symbolized by t, would be the amount of seconds it took an object to fall this vertical distance, and g being the gravitational force of 9.8 acting on it before it hit the ground.Time can be found more directly by using the equation=2yo/g . Y symbolizes the initial velocity in the y or vertical direction. If the ball were traveling along the x-axis or in a horizontal direction, the equation would be x=vt. In the horizontal direction, the force of gravity is not significant factor because the object is already on the ground. However, if an object were shot out of a gun for example , in a horizontal direction , then the force of gravity would directly act upon the object on its descent .
First of all, it was able to conclude that wind going upward is the most influential wind direction to the performance and the results of ski jumping event. This is because ski jumper flies more than 92cm all the time. In addition, wind coming from South has considerable impact on the ski jumper. The reason for this is because the wind from South enables ski jumpers to fly near 90, which is far distance compared to other directions of the wind. The key point is that when these two directions combined, this provides the chance to ski jumper to fly the farthest.
P2 Fitness test for the main components of fitness There are 8 components of fitness which are, cardiovascular endurance, strength, muscular endurance, flexibility, speed, reaction time, agility and coordination. 1. Cardiovascular endurance This is also known as an aerobic endurance or stamina, which is the ability to repeat an activity for a length of time without becoming tired. A fitness test for this component is the cooper or bleep test. Cooper Test/Beep test Cardiovascular endurance can tested for by using various maximal tests which test your limit of endurance in some exercise .
KINETIC AND POTENTIAL ENERGY WORKSHEET Name:________________________ Determine whether the objects in the following problems have kinetic or potential energy. Then choose the correct formula to use: KE= 1/2 m v2 PE = mass x gravitational acceleration (9.8m/s2) x height OR Weight X Height Energy= joules Weight= Newton Mass= kilograms Velocity= m/s Gravitational acceleration= (9.8 m/s2) 1. You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. The ball has ______________________ energy.
