Darcel and Chandra are sitting in the park after physics class,
and they notice some children rolling various objects down a slight
incline in the sidewalk. Darcel is curious how the masses and
shapes of the objects affect their motion, and Chandra says that it
might be fun to think about the energy of motion associated with
rolling objects. The friends decide to use the simulation to
explore the motion and energies of various objects rolling down an
incline.

Rolling and Torque Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and mass of 1000 kg (HUGE SPHERES, think Indiana Jones). The difference is how the mass is distributed. One sphere is completely solid with mass equally distributed throughout it. The second mass has all of its mass distributed at the edge of its radius in a thin shell. So, one...

10. A hoop, solid sphere, and solid cylinder each have the same mass and same radius. When rolling down the same incline, which has the greatest torque from gravity on it? a. the hoop b. the sphere c. the cylinder d. They all have the same torque.
Rotational Kinetic Energy and Conservation of Energy Ranking Task
The five objects of variousmasses, each denoted , all have the same radius. They are all rollingat the same speed as they approach a curved incline. Rank the objects based on themaximum height they reach along the curved incline.Rank from largestto smallest.

A solid sphere and a hollow cylinder of the same mass and radius have a rolling race down an incline as in Example 13.9. They start at rest on an incline at a height habove a horizontal plane. The race then continues along the horizontal plane. The coefficient of rolling friction between each rolling object and the surface is the same. Both have mass M Both have radius R. Write an expression for the distances that each object will roll...

Q10 A hollow sphere and a hoop of the same mass and radius are released at the same time at the top of an inclined plane. If both are uniform, (1) Which one reaches the bottom of the incline first if there is no slipping? (2) A uniform hollow sphere of mass 120 kg and radius 1.7 m starts from rest and rolls without slipping dow an inclined plane of vertical height 5.3 m. What is the translational speed of...

A uniform cylinder of radius r15.0 cm and mass m 1.70 kg is rolling without slipping on a horizontal tabletop. The cylinder's center of mass is observed to have a speed of 4.60 m/s at a given instant. (a) What is the translational kinetic energy of the cylinder at that instant? J (b) What is the rotational kinetic energy of the cylinder around its center of mass at that instant? J (c) What is the total kinetic energy of the...

A solid sphere, a solid disk, and a thin hoop are all released from rest at the top of the incline (ho = 20.0 cm). a) Without doing any calculations, decide which object would be spinning the fastest when it gets to the bottom. Explain b) Again, without doing any calculations, decide which objďct would get to the bottom first. Hint: which one has greater translational speed? Think CoE! c) Assuming all objects are rolling without slipping,...
