Three magnets are placed on a plastic stick as shown in the image. Explain how the magnets need to be rearranged so that they stick together and why rearranging them this way allows them to stick together.

The magnets need to be arranged so that the blue side of one magnet faces the red side of another magnet. When they are arranged in this way, the opposite poles of the magnets will be closest together. Because opposite poles attract, the force of the magnets will make the magnets stick together.

Explanation:

The magnets need to be placed with red closest to blue.

Opposite poles attract.

The magnets will be attracted to each other with enough force to stick together.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
