Answer:A pendulum illustrates the conservation of energy. The pendulum has the most potential energy - the energy of position or stored energy - when it is highest above the ground. It has the most kinetic energy - the energy of motion - when it is moving the fastest. As the pendulum swings downward, the potential energy changes to kinetic energy. As it swings upward, the kinetic energy changes to potential energy. The back-and-forth swinging of a pendulum is simple harmonic motion - motion that repeats periodically. The period of a pendulum is the time needed for one complete swing back and forth. This period is constant; it changes only if the length of the pendulum is changed. Ask student to time the periods of their pendulums when the pendulums swing through a longer distance (larger arc) or shorter distance (smaller arc). They will discover that the periods are the same. Have the students then change the mass by adding one or more washer to their pendulum. When the students time the periods, they discover that the period does not change if the mass is changed. Ask students to experiment to find what will change the period of the pendulum. Students will discover that the period will change if the pendulum’s length is changed.

Although Grady assisted Georgia’s economic growth, what is he criticized for?
antoniya [11.8K]

Henry W. Grady, born in Athens in 1850, Grady became well known for his great ability as a writer and debater. After leaving the University of Georgia, he studied literature and history at the University of Virginia in Charlottesville and later on persued a career in journalism. Throghout his life as a journalist, Grady managed several papers in the South and became an influential political figure in that with his arguments and easiness of conviction, he was able to push forward the nominations and candidacies of several of his fellow political members at the Atlanta Ring, a group of proindustry Democrats who believed firmly in the ideals of the New South. Grady firmly believed in the need to promote industrial investment from the North, a reinitiation of the Southern industries, a change in the trust between North and South to increase investment. When he returned to Atlanta, Grady dedicated himself to underlining the magnificence of Atlanta as a center over Macon, Athens and Augusta. Despite the favorable effects that Grady had to improve the economical growth of Georgia, but most importantly of Atlanta, he was highly critized by his peers and fellow Georgians for exposing the South with his ideas and policies to the control and subjugation of the North, selling the South to the North and inviting oppression on Souther farmers. He was also critized for attempting to show the North a more bening stand on the issue of freed slaves and slavery. Grady died on December of 1889.
