The air-track can make the trolley frictionless by testing the velocity with different weights and shows that F=ma. Research question: How much acceleration does the frictionless trolley has? Aim: Use the air track to measure the acceleration of the no friction trolley by hanging with different mass of weights. Apparatus: * 1 air track * Weights (40g‚ 50g‚ 60g‚ 70g‚ 80g‚ 90g‚ 100g) * 1 string (bigger than 200cm) (plastic) * 1 frictionless trolley (160g) * 1 pair of scissors

Prepare a set-up to record the motion of a trolley on a runway as shown below. While necessary‚ adjust the runway for friction compensation. 2. Start data-logging. Use 1 elastic thread to pull the trolley along the track. The thread should be stretched by the same

The rougher the surface‚ the shorter the stopping distance. 2. The larger the mass the further the stopping distance. Introduction: The purpose of this research was to investigate how different surfaces as well as different mass effect the stopping distance of a physics trolley after rolled down a ramp. The aim is to test the hypothesis

culture therefore‚ helping break down racism and spread a wider acceptance in the community inside and outside of baseball. Jackie Robinson was the first African American to play major league baseball during the modern era. Before he signed to the Dodgers‚ baseball in the black community was considered just a pastime and not a career. Integration into professional baseball was unfathomable. Looking through all of the years of baseball in America that led up to Robinson’s debut of 1947 in Brooklyn.

Jackie Robinson was the first African American to play in the MLB; he made his debut on April 15‚ 1947‚ for the Brooklyn Dodgers where he played infield and outfield (“Robinson”). Jackie Robinson was an “experiment” for the Dodgers‚ Branch Rickey‚ the Dodgers manager‚ wanted to show the MLB that African Americans could play ball and keep calm while someone was being racist to

After he arrives to London he is saved from stealing an apple and possibly being caught by Dodger. Afterwards Dodger takes him to the slums where he joins a group of thieves that work for Fiegin. Fiegin teaches the boys how to pick-pocket and puts a roof over their heads but sees them as nothing more than an investment. Even though this type of lifestyle

The second law states that the acceleration of an object is dependent

When the Major League Baseball program started in 1869‚ the teams were all white. This meant that no African-Americans were allowed to play. In 1945‚ Jackie robinson was asked to sign with one of the Brooklyn Dodgers’ farm teams‚ the Montreal Royals. The Dodgers’ president‚ Branch Rickey signed Jackie because they wanted to start integrating baseball (Jackie Robinson‚ 1994). Branch Rickey didn’t want to pick just anyone to be the first African-American in the Majors‚ but he picked someone

Materials: Trolley Elastic cords for accelerating trolley Rod for attaching elastic cord to trolley Ticker-timer with power supply unit Ticker-tape Sellotape Process: 1.Thread a length of ticker-tape through a ticker-timer and attach the end to a trolley. 2.Pull a trolley with a fixed force along a bench. Loop one end of the elastic cord around a rod attached to the trolley. Keep the force constant by making sure that the cord is always stretched by the same amount as the trolley moves. Practice
