Newton’s cradle FAQ
What is newton’s cradle
Newtons cradle is a device that visually demonstrates how the conservation of energy works.
How does newton’s cradle work
You can image the outside ball swinging and hitting the interior static balls, instead of the energy jumping out of the balls and into the air( this would take a lot of energy). The energy flows like an invisible ghost through the static balls until it reaches the end ball and, instead of jumping into the air the energy stays in the ball and converts to movement energy.
Newton’s cradle tricks
Instead of the pendulum motion of one ball hitting from either side you can try and swing multiple balls at one time.
A very cool thing to do is stagger a few balls slowly together, the resulting force of each of the balls hitting of each other echoes through the balls and actually increases the swing.
How to make a newton’s cradle
If you would like a weekend science project then why not make a Newtons Cradle. There are a few things you will need for this project:
- 5 pieces of string or fishing wire cut to the same size.
- 5 Marbles
- Hot Glue Gun
- Craft Sticks
- Start by assembling a frame by using a picture of a newtons cradle as an example.
- Once the frame is built glue a marble directly in the centre of each of the pieces of string.
- Attach each piece of string to the frame and separate them by the exact distance.
- To finish, glue the pieces of string to the frame for more security.
How long does newton’s cradle swing
In a very specific environment, in a vacuum a newtons cradle swing could last forever!. However, as on earth here we dont have the very specific environment needed, a newtons cradle will stop moving eventually. How long it will take a newtons cradle swing to stop is a really hard question to answer. Your basic newtons cradle swing sitting on a desk will stop eventually, it depends on a few things:
- How high the starting point of the first ball is
- how heavy the balls are
- how long the wires are
Who invented newton’s cradle
You might thank, ha, easy answer! Although the physics demonstrated in an Newtons cradle are based on Isaac Newton he did not invent the cradle. Instead an English Actor named Simon Prebble built the device in homage to Isaacs laws of conservation of energy.
Why do the balls of the newton’s cradle eventually stop?
If the balls set in motion could conserve all of their energy then they would never stop. However as we are on earth they are subject to all the same forces that restrict and use their energy. A newtons cradle loses energy through these ways:
- Friction of the air
- Gravity pulling the balls down towards a central point
- Sound energy lose when the balls collide
- Heat energy lose as a result of balls colliding
If we could stop each of these energy loses, the newtons cradle would go on forever.
