In the month of October, the 5B science class studied pendulums at the Glenridge elementary school. They studied pendulums so they could understand different forces. They got an assignment to experiment with pendulums.
What is a pendulum?
A pendulum is something hanging and swinging freely from a fixed point. A grandfather clock might use for timekeeping a pendulum that swings back and forth.
Above is a pendulum. Weight swings back and forth around the vertical axis. The vertical axis is the blue dotted line in the picture above.
There are three forces at work on a pendulum: Gravity, Friction and Opposite Force. Gravity is a force that pulls things down closer to the center of the Earth. In the picture above gravity is pulling the grey ball down to the ground. Friction is a force that allows the object to swing freely from the fixed point. The weaker the friction is, the more freely the ball will swing.
Opposite force is a force that pushes against gravity. When the ball swings up, the opposite force is pushing against gravity.
Cool
ReplyDeleteI liked you details and moving picture it built up tension and that was one of the things that made it so great!
ReplyDeleteand great connection to science
ReplyDeleteCool image. I like how it moves because it is just what we did in science. I know it's a gif. I hope you can teach me how to put a gif on my blog articles.
ReplyDeleteHow did you add a image?
