What makes top spins longer?

What makes top spins longer?

Heavy tops spin for a longer time than light ones when launched at the same speed. The faster they’re spinning when launched, the longer they spin. The combination of mass and speed is known as momentum. Mathematically, momentum is mass times speed.

Why will a spinning top not spin forever?

As it spins in its upright position, it rotates around an invisible vertical axis. The principle of conservation of angular momentum holds that the top would keep spinning indefinitely if there were no other external forces acting upon it.

How long does the forever spin spin?

Nimrod explained that the motorised spinning top’s long-lasting spin is due to its small size and minimal energy consumption. Though the record attempt was stopped at just over 27 hours, Nimrod claims the spinning top can rotate for up to 30 hours.

What is the longest spinning top time?

27 hours 9 minutes and 24 seconds
The spinning top also holds the Guinness World Record title for the longest running mechanical spinning top. The exact time duration of its world record spin is 27 hours 9 minutes and 24 seconds.

How do ballerinas spin so fast?

Train hard. Ballet dancers train hard to be able to spin, or pirouette, rapidly and repeatedly. They use a technique called spotting, focusing on a spot – as they spin, their head should be the last bit to move and the first to come back.

Can you make something spin forever?

Well, again no. As empty as space is, it does have some forces – some particles there and there, radiation from the stars, gravity of some planets. It could not spin forever, but it would come close to it, actually. Meanwhile a fidget spinner would spin much shorter, because of its internal friction in the bearing.

What’s the easiest way to make a spinning top?

One of the easiest ways to make a spinning top is with a plastic lid or bottle cap. Choose the lid you want to use, wash it off, and pierce it through the center with an ice pick or nail. Next, slide a toothpick or wood skewer about halfway through the hole in the lid to create the spinner.

How long does it take for a spinning top to dry?

Wait for the glue to dry for at least 2 hours before spinning the top. Seeing the top will make you want to spin it right away, but it will last longer if you wait! Set the top aside on a countertop exposed to open air. To create a stronger bond, let the glue dry for 24 hours.

Why does my top spin all the time?

Pins are not very sturdy, and it is easy to bend them out of shape. If the tip of the top is not exactly on the axis of rotation, it will make the top wobble, and make the point slip on the floor as the top spins, losing energy due to friction.

What makes a heavy top spin faster than a light top?

A heavy top with mass concentrated far away from the center will have more energy when spinning than a light top (it will also push down harder on the tip). Follow-up on this answer.
