motion can be split into two separate dimensions of movement. The first being constant motion in the horizontal x axis witch neglecting air resistance should stay constant throughout the projectiles path. In the vertical y axis we have constant acceleration due to gravity toward the ground. These two motions are linked in time witch allows you observe the instantaneous characteristics of the projectile. Time is the connecter between the equations so you can salve for time in one equation and plug

TO: Hope Weiss FROM: Nap Paholio DUE DATE: December 11‚ 2015 SUBJECT: Simulation Project Introduction The objective of this lab is to simulate the motion of an untuned vehicle’s suspension driving down an uneven surface. In terms of pitch and bounce‚ the goal of the simulation is to optimize and tune the car’s suspension to ensure an ideal ride over a bumpy surface for the driver. Experimental Method The suspension of car works with two- degrees of freedom: the pitch and bounce. The combination

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts
