WEEK 2

• Aristotle believed that a pendulum slowed down as it approached its resting place
• Aristotle believed heavier objects fall faster than smaller ones
• Aristotle believed that earth is the center of the universe
• Galileo showed a pendulum does not slow down which he called the law of pendulum.
• Galileo monitored the movement of the stars using a homemade telescope to show that the sun is the center of the universe
• Natural motion states that objects that belong to earth falls faster than those made more of fire or air
• Violent motion is the state of motion that prevents that attainment of natural progression of motion: either frustrates or go against natural motion
• Projectile motion is a form of motion experienced by an object or particle that is projected near the Earth's surface and moves along a curved path under the action of gravity only.
• Natural motion is largely vertical motion
• Violent motion is largely horizontal motion
• A constant amount of force is needed to be applied to objects to keep them moving in horizontal motion
