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.

Answer:
Freedom of faith was a big motivation for the English. In 1620, a group of settlers left England to seek the New World. Many were separatists, who believed the Church of England was dishonorable. By seeking out the New World, they were trying to break away and worship their own faith.
Answer:
Architectural aesthetics and Urban planning in America
Explanation:
City Beautiful Movement was a great reform in urban planning and modern architecture. The shapelessness of American cities emerged into more developed and advanced with an extraordinary speed between 1860 and 1900. It promoted beauty to create moral and civic virtue.
Columbian Exposition 1893, Chicago, celebrated the 400th year anniversary of Christopher Columbus' arrival in America.
Both the movement and Columbian Exposition advocated the philosophy of beauty and the value of aesthetics required to promote harmonious social order.
