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:
1. To defend Christianity & 3. For riches
Explanation:
During the Middle Ages (medieval time) the Crusades came up as 'expeditions' to recover holy land taken by Muslims.
People involved on Crusades were seeking the security of the Church and their holy territories.
Men also took this opportunity to gain more resources and power from lands they were recovering. While promoting Christianity as the main and only religion to follow.
I believe Washington said "On the prospect of the happy termination of this insurrection I sincerely congratulate you; hoping that good may result from the cloud of evils which threatened, not only the hemisphere of Massachusetts but by spreading its baneful influence, the tranquility of the Union."
I hope this helps you:)
Answer: The Industrial Revolution sparked a greater need for cheap raw materials
Explanation:
The Industrial Revolution was the improvement of production processes in Europe such that goods were being produced way more efficiently than before. This meant that industrial goods could be mass produced in higher quantities.
To produce manufactured goods however requires raw materials which was lacking in Europe at the time so they sought to get these materials from other places and cheaply if they could. They therefore colonized areas rich in raw materials such as Africa to get these materials at low low prices.
1) it helped to be able to make more merchandise
2) it made people get more money in buisnesses
