Conclusion In this experiment I tested different light intensities. I tested a normal fluorescent light bulb‚ a 100-watt light bulb‚ a 25-watt light bulb‚ and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm due to the fact that it fried the plant. The 25 watt plant grew the next highest at 120 mm. The 15-watt light bulb grew tall fastest‚ but then slowed down and stopped at 98 mm you would want to use this

Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer‚ a force sensor

of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total linear momentum of the system cannot change. There are two simple types of collisions‚ elastic and inelastic. If the total kinetic energy of the two systems is conserved then the collision is known as elastic

Experiment 1.7: Graphical Analysis of Motion Introduction To graphically analyze motion‚ two graphs are commonly used: Displacement vs. Time and Velocity vs. Time. These two graphs provide significant information about motion including distance/displacement‚ speed/velocity‚ and acceleration. The displacement and acceleration of a moving body can be obtained from its Velocity vs. Time graph by respectively finding the area and the slope of the graph. Data Tables – Part I Displacement

Buoyant Forces The purpose of this lab is to calculate buoyant forces of objects submerged in water. The first step in the lab was to measure the mass of a metal cylinder‚ which was found to be 100g‚ and then to calculated it’s weight‚ which was .98 newtons. Then next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g ‚ this was found to be 88.5grams. Knowing these two numbers‚ the buoyant force that the water

Miriam Karunakaran Physics Honors Period 6 Physics Kinematics Lab Report Kinematics is the study of the motion of bodies without reference to mass or force. This lab aided students in observing kinematics by giving them a visual graph to look at from experiments previously performed. Variables used in this lab were “x” for position of the object‚ “v” for velocity of the object‚ and “a” for acceleration of the object. Understanding the graphical representation of

PHYS 221 Experiment M10 Harmonic Motion of a simple Pendulum Jacob LaMarre Group members: Josh‚ Courtney‚ Ashley Abstract: Determine the acceleration due to gravity using a pendulum. Introduction: A simple pendulum consists of a mass suspended by a length of string. When set Oscillating‚ the mass will have a period “T” given by the following equation. This equation shows the only variables that affect the rate at which the pendulum swings is the length “l” that is measured to the center
