This is due to the friction caused by its contact with the ground. If the contact point were large, then every rotation would cause a lot of friction, and slow the top down faster. And as we mentioned before, the top needs that speed to even out the imbalances it experiences. The other factor that will keep a spinning top on its feet for longer is the momentum it has.
The more momentum it has, the more energy it has and therefore the harder it is to stop. The two main stopping factors on a top are friction at the base, and the far more troublesome air resistance as it spins. The more momentum the top has, the more work the air needs to do to slow it down. To increase the momentum of a top the easiest method is to make the top heavier. As momentum is mass times velocity, the heavier the top, the more energy it carries. Basic top supplies from Part 1 extra paper plates and 8 rubber stoppers pencil masking tape stopwatch or clock with a second hand.
Items to add weight to tops, such as: nuts and bolts washers paperclips bulldog clips plasticine. How and why do tops spin in different ways? How can we use observations to help us learn more? Teacher Tip: Depending on how much experience your group has had with tops and spinning toys, you may want to start with time for the students to play with a variety of commercial tops.
Hint: Tops spin well on uncarpeted floors. If you have a carpet which interferes with your tops, spin them on the lids from ice cream pails. Tops figure into many cultural traditions. Investigate, for example, dreidels, giant wooden tops used since the tenth century in Ta Hsi in Taiwan, or those tops used by the Haida and Tsimshian of the Pacific West Coast.
Hint: Try using yogurt containers, rubber balls, CDs or pizza pans as alternative flywheels. For example, if you add weights and also try a new method of launching your top, you will not know which caused the change in top behaviour.
Teacher Tip: This might be a good time to introduce your students to using charts and tables to keep track of results. A top made with a felt marker or a pencil as a stick creates surprising and beautiful artwork. Wool can be spun with a hand spindle, which uses a spindle whorl as a flywheel to add momentum to a spinning stick. Coast Salish artisans have traditionally decorated their spindle whorls in a way that creates fascinating patterns as the whorls are spun.
Contemporary artist Susan A. Point creates decorative spindle whorls in this tradition. Are you ready to get rolling or rather, spinning? Mathematically, momentum is mass times speed. The momentum of spinning and rolling things is called angular momentum. Objectives Build tops and use various methods to make them spin. Investigate the concepts of inertia, momentum, force and centre of mass, as they apply to tops.
Prompt them with questions like: Does anyone own one? What does it look like? Have you ever played with one? What can you tell me about the way they work and behave? Where can one find tops in our everyday world? Has anyone ever spun around or been a top? Has anyone ever ridden a top? What was that like? Did you notice or do you remember anything special about tops?
Build the top. Find the centre of your paper plate by balancing it on your finger. If the plate balances, your finger is at the centre of mass. Use the nail to poke a hole through the plate at that point. Dip one end of a 25cm-long dowel in liquid soap, which will allow the dowel to slide through the stoppers more easily. Put one stopper on the dowel and slide it along about a quarter of the length.
Slide the other stopper on from the bottom, so that the stoppers sandwich the plate, and push the stopper tight up against the plate. There should be about 2—3cm of dowel showing under the plate. Launch the top. Be sure to tighten the rubber stoppers after each launch they will work themselves loose. Rubber band launcher: Attach two rubber bands together in a chain. Here are a few things that might help you start your collection, become a spin master or inspire you to pick something original for your loved ones.
