Solving Part A: Center of Mass in One Direction 1. 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 is uniform about the axis of symmetry. Therefore‚ the horizontal center of mass will be at the exact

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

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 =

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
Premium Acceleration Kinematics Velocity
Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium‚ the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon‚ When light travels from air into water‚ it slows down‚ causing it to change direction slightly. This
