why does a solid ball roll faster than a hollow sphere

Watch the cans closely. Think of a lever, it's easier to move something the farther away your side and the it are from the axis. Ignoring frictional losses, the total amount of energy is conserved. Theory behind the relationship between the mass of a cylinder and the time taken for it to roll down an incline - air resistance? Empty, wash and dry one of the cans. Follow him on Twitter @BenFinio. This isn't true. If there are two spheres (hollow and solid) with equal mass and radius and we want to find the hollow sphere without using any equipment. Let go of both cans at the same time. Sorry to ruin your day, but this actually has to do with Inertia and distribution of energy. How to remove unique strings from a textfile? The mass, partnered with gravity as a force and the lesser friction due to less contact with the surface allows the solid sphere to roll the fastest. @Gert Thanks for your comment. If an object is descending in a gravitational field it is trading potential energy for kinetic energy. rev 2020.11.5.37959, The best answers are voted up and rise to the top, Physics Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. Kinetic energy Hold both cans next to each other at the top of the ramp. Should I speak up for her? ), Prop up one end of your ramp on a box or stack of books so it forms about a 10- to 20-degree angle with the floor. (Although they have the same mass, all the hollow cylinder's mass is concentrated around its outer edge so its moment of inertia is higher.). It's all about the weight distribution. Kinetic energy depends on an object’s mass and its speed. More to explore Is there any factor that would determine whether this difference would be noticeable (such as length of incline, angle of incline, etc.)? Had the liquid been much thicker, the result would be much different, but in this case, the difference in speed between the two bottles was obvious. Each centimeter of vertical drop, as the pieces roll down the ramp, gives them a certain amount of energy, converted from [gravitational] potential energy to kinetic energy (of the two kinds I just described). Science Activities for All Ages!, from Science Buddies, This activity brought to you in partnership with Science Buddies. Physics In this GIF, why does the solid sphere go faster than the solid cylinder and the hollow sphere and cylinder? Try this activity to find out! It WAS very different. I'm trying to find a real life application of this phenomena. Draw a free-body diagram for each of the objects and apply the equations of motion; you'll quickly see why the weight distribution is so important. The answer is that the solid one will reach the bottom first. ), A hollow sphere (such as an inflatable ball), A solid sphere (such as a marble) (It does not need to be the same size as the hollow sphere.). Mass and radius of the cylinders should not matter. Hollow Cylinder vs Solid Cylinder [closed], Creating new Help Center documents for Review queues: Project overview. Given that, lets start our analysis. Explain Like I'm Five is the best forum and archive on the internet for layperson-friendly explanations. The empty bottle behaved as you would expect an empty cylinder to, rolling slower than the full bottle.
