One World: Motion Topic: Write an article that explores how the Physics of Motion is (or can be) used to solve a specific problem in a local or global context. Millions of people everywhere around the world make use of the principles of motion to travel up and down quickly within a tall building. The use of elevators has been around since ancient medieval times since then has grown from being powered by a hoist and winder to electric and hydraulic motors1. An elevator

Practice Projectiles (Source for the first five problems WWW.MIAMI-BEST-MATH-TUTOR.COM‚ 1. 1. A physics book slides off a horizontal table top with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Find the height of the table top above the floor; the horizontal distance from the edge of the table to the point where the book strikes the floor; the horizontal and vertical components of the book’s velocity‚ and the magnitude and direction of its velocity‚ just before

Curvilinear Motion Projectile Motion When the player hits the “Sepak”‚ the motion of the “Sepak” is called projectile motion. The “Sepak” itself is called projectile. The “Sepak” will follow a parabolic path called trajectory especially if air resistance is negligible. Two coordinates are usually used to describe projectile motion: horizontal and vertical axes. The horizontal distance traveled by the projectile is called the range. While the vertical distance‚ that is‚ the distance from where

Matthew Mannetta Simple Harmonic Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Procedures: Create a ramp that can be a repeatable launcher for your marble‚ one in which the marble will not bounce once hitting ground surface. Take 2 photogates and place them 10 centimeters apart‚ along the edge of the table. (d) The photogates are instruments that will time the marbles speed. Measure the height (h) carefully‚ in which is vertical to the floor. Time the marble several times as you launch it from the ramp; make sure to catch the marble as it leaves the table. Use the

The Physics and Components of Medieval Projectile Launchers Before the age of cannons‚ gunpowder‚ and modern warfare‚ projectiles were fired using machines generally identified as catapults. Civilizations in the middle ages were the ones to use the catapult the most‚ utilizing basic laws of physics to hit their target. We will look at different designs in catapults and how they function. Even today‚ launching projectiles is a lesson in physics. Catapults are no exception. From the great minds of

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the
