Animation 1
[]

This animation shows the relationship of interference between two different waves. When both the waves are opposite of each other this is an example of destructive interference. This is when the black wave is not visible. The sum of the two waves at their destructive interference position would be less then at least if not both of the waves. The point where the two waves line up is an example of constructive interference. This is when the black wave is at its peak. At this point the sum of both the waves is bigger than either of the singular waves. This helps the the relationship between two different waves and how they interact with each other to create different types of interferences. SImply click on the link above and the animation should start by itself.

This animation shows the different forces that act on a pendulum while in motion. The forces that this animation show are the force of gravity, tension, and the sum of both the forces. This diagram demonstrates that while the pendulum is hanging that the force of tension is always bigger than the force of gravity. If the force of gravity was larger then the ball would just fall towards Earth. This animation also demonstrates which direction the sum of the forces arrow is pointing which helps people understand why the pendulum moves the directions that it goes.
