Learn how energy is transfered from one object to another in thisnewtons cradle activity.
For thisphysics experiments for kids, you will make anewtons pendulumto explore how what happens when two objects colide.
ThisNewtons cradle projectdemonstrates the conservation of energy and momentum when the balls collide.
While the idea of doing aphysics science projectwith your kids probably sounds super complicated, dont worry its not!
Now cut FIVE 17-inch long pieces of thread.
Tie the center of one thread around the pushpin in the bouncy ball.
Repeat with all 5 bouncy balls.
Newton cradle pendulum
double-check all bottles are filled with liquid and have their cap securely in place.
Place bottles at four corners of a rectangle that is 6 inches wide and 10 inches long.
Set bamboo skewers across the bottles to form a rectangle.
The shorter side wil have some of the stick hanging off on both ends.
Now tape the skewers to the lids of the bottles to hod them in place.
Easy Science Experiments
They should all hang so they are almost touching and as low as possible.
Add tape to the stick to ensure that each string doenst slide around.
Newtons Pendulum
Now its time to try your Newtons Cradle!
Carefully pull back one ball from one end and let it go.
Fun Physics Experiments
Watch the ball on the other end fly out!
Newtons cradle explanation
Whenever two objects collide the total amount of kinetic energy stays the same.
How much energy depends on the objects mass and the speed at which the items collide.
Want to take it a step farther?
What if you tried using ping pong balls which are lighter than the bouncy balls.
Would it still work the same?
