Keep a Marble in Motion for 2 Minutes - Ideas & Your Thoughts

[Steve B.]

How can I keep a marble in motion for 2 minutes?

I've had 2 suggestions so far:

*A simple way would be to put a marble in a bucket and move the bucket so the marble spins along the walls.

*Another idea is to have a teeter-totter, using a long plastic tube. Have a string attached to each side. Put he marble in one one of the tube and pull the other one down. Then alternate pulling an end down to keep the marble moving. Have and caps on the tube so the marble can't escape.

But, if i can only touch it once and that's to start if off. how can i do that way?

Your thoughts?

I would suggest using the principles of inertia and momentum to keep the marble in motion for 2 minutes. Inertia is the tendency of an object to resist changes in its state of motion, while momentum is the product of an object's mass and velocity.

One way to keep the marble in motion for 2 minutes is by using a ramp. Place the marble at the top of the ramp and give it a small push to start it moving. The ramp should be smooth and at a slight angle, so the marble can roll down without any obstacles. This will allow the marble to maintain its momentum and continue rolling for 2 minutes or even longer depending on the angle and smoothness of the ramp.

Another way to keep the marble in motion is by using a pendulum. Attach a string to the marble and suspend it from a fixed point. Give the marble a small push to start it swinging. The pendulum motion will keep the marble in constant motion for 2 minutes or longer.

You could also try using a series of dominoes to keep the marble in motion. Set up a line of dominoes with a small gap between each one. Place the marble at the beginning of the line and give it a push. As the marble knocks over each domino, it will continue moving and knocking over the next one. This will keep the marble in motion for 2 minutes or longer depending on the number of dominoes used.

Overall, the key is to minimize friction and provide a smooth surface for the marble to roll on, as well as using the principles of inertia and momentum to keep it in motion. I hope these ideas are helpful and inspire you to come up with even more creative ways to keep the marble in motion for 2 minutes.
