Is the object that can both stand and roll a ball, right or wrong?

No, for example, cones can also be rolled.

So it's uncertain.

If the original work is placed horizontally, it is an object that can be rolled, but if it is to be counted and intelligentized, it can also be said to be an object of the great text.

The original work is a material that can be rolled, but as long as the conditions are right, I think it can be done.

It belongs to an object that can roll or an object that can be stabilized, the cylinder can be said to be a relatively stable support, and the column is worth a thousand gold.

I think the cylinder must be a rolling tooth in the first place, because it is round, so it is very convenient when he is in Guangdong, so when he is vertical, can he be stable? But it can't be stable when it's in it.

(Attach the object that is a cuboid to the box, and the object that is a cube to the cube) Connect the object that is a cylinder to the cylinder.

A cylinder is an object that can be rolled when it is laid flat, and it is an object that can be built when it is erected, so the cylinder can be rolled and stabilized!

Do people belong to rolling objects, or do creatures help me move objects? It is the animals that go, so the whole one goes and rolls.

All belong, the cylinder can be both rolled and steady, so it all belongs!

Hello friend, if the cylinder is put down, it can roll it, it is a rolling object, if you give it a stand, it is a stable object, thank you.

If it is a cylinder, it can be said that it is an object that can be rolled, can it be steady? How can that also be structured according to him? If you make a roof like our timber and timber, won't he be able to hold it firm?

A cylinder is an object that can be rolled and an object that can be built steadily, a cylinder is round, can be rolled, is standing when building, and can be built steadily.

As long as it depends on the specific situation, under normal circumstances, there is no problem at all, it is okay, or relatively speaking, the effect is relatively good, and the effect achieved is very good.

I wish we all this thing that can roll, he rolls and rolls.

Aid is widely used in architecture, because the column is easy to roll, so it must be fixed in order to be in the city, otherwise it is easy to roll away and affect the actual use effect.

Note, it belongs to the kind of object that can roll, and this kind of object can indeed pick up the kind of object, so this kind of object does give people a very stable effect, so this is generally used now.

The original book belongs to objects that can be rolled, because he is a cylinder, so he does not have any obstacles to rolling, so it is said to belong to objects that can roll.

Then your Cantonese is the one that keeps on big in various problems, just three triangles, and triangles are relatively stable interfaces.

The cylinder should be an object that can be rolled, but there are some objects that can be stabilized! Because of the original work, there is a horizontal release, that is, rolling, vertical placement, and the whole is cooling, so it should be both!

The rock master is still an object that can roll, and we can also replace his big problem, after all, it can bring you a better help and water.

It's an object that can roll.,You should check some news about this cylinder.。

It depends on how you go to build it, if you are vertical, it can be relatively stable, but it will roll horizontally.

a. A football rolling on flat ground, the football has mass, speed and kinetic energy; The soccer ball is on flat ground, is not lifted high, and does not have gravitational potential energy which does not fit the topic

b. The barbell is lifted by the athlete, the barbell has mass, is lifted high, and has gravitational potential energy; But the barbell does not move, does not have kinetic energy, and does not fit the topic

c. A bird flying in the air, the bird has mass, speed, and high altitude, and has both kinetic energy and gravitational potential energy, which is in line with the topic

D. The flattened ball has undergone elastic deformation and has elastic potential energy, which does not meet the meaning of the topic, so choose C

Yes. Due to the different frictional forces on the slope at different angles, the velocity and kinetic energy are different when they reach the bottom of the slope, and the friction force after reaching the horizontal plane is equal, so the distance that can roll is different.

Ideally, the distance is the same.

Suppose the friction of the slope is zero.

Because of two processes.

Both are the conversion of the object's high potential energy into kinetic energy.

Highly consistent. The potential energy is also the same.

Then the distance of the roll is the same.

Hope it helps.

They can all roll, but the direction is different, so it has to be determined by the question.

If the emphasis in that question is that an object must be rolled, then you can only choose a circle, not a cylinder.

Yes, the roll of the cylinder is along the cylindrical surface, and the ball can roll at will.

When a spherical object rolls, it can be seen as the wheel axle turning, with a fixed radius of rotation. According to the knowledge of mechanics, it is easier to rotate when the force (vertical axis of rotation) multiplied by the radius of rotation is equal to the rotational torque and the rotational torque is unchanged.

That's right, the sphere is made up of many, many faces, so it's easy to roll.
