AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

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

Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

(a) Container A‚ because its bottom has the greatest surface area. (b) All three containers have the same pressure at the bottom. (c) Container A‚ because it has the greatest volume of fluid. (d) Container B‚ because it has the least volume of fluid. (e) Container C‚ because its bottom has the least surface area. 2. Three solid objects are floating

Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then
