a rigid body rotates about a fixed axis

A rigid body rotates about a fixed axis when the whole body turns around a point that doesn’t move. This can be demonstrated with a spinning top. The point around which the top rotates is called the axis of rotation. The top will rotate until its center of gravity is directly over the axis of rotation.

The axis of rotation is always perpendicular to the plane of rotation. The plane of rotation is the plane that contains the axis of rotation and the points on the body that are rotating.

The speed of rotation is measured in rotations per minute (rpm).

## When a rigid body rotates about a fixed axis?

A rigid body rotates around a fixed axis when all the points on the body move in a circular path around that fixed axis. This type of rotation is often seen in objects such as wheels or gyroscopes.

The rotation of a rigid body around a fixed axis is a very orderly process. All the points on the body move in a circular path around the fixed axis. The path of each point is always perpendicular to the axis of rotation. In addition, the points on the body move at the same speed and in the same direction.

This type of rotation is very stable. The body will continue rotating around the fixed axis until an outside force acts on it. For example, a car’s wheels will keep rotating as long as the engine is providing power to them. If the engine is turned off, the wheels will stop rotating.

Rigid body rotation around a fixed axis is often used in devices such as gyroscopes. Gyroscopes use the principle of rigid body rotation to keep their orientation fixed. This allows them to be used in navigation and other applications where a stable orientation is important.

## When a rigid body is rotating about a fixed axis which of the following is same for all its particles?

A rotating rigid body is an object that is rigidly held together and is rotating about a fixed axis. For all particles in the body, the direction of the force exerted on them by the rotating body is perpendicular to their direction of motion.

## When a rigid body rotates about a fixed axis chegg?

When you rotate a rigid body about a fixed axis, there are two types of motion that can take place: rotation and translation. Rotation is the spinning of an object around a fixed point, while translation is the movement of an object in a straight line. In order to understand how rotation affects a rigid body, let’s first take a look at what happens when you rotate an object in space.

If you take a spinning object and move it to a new location, the object will continue to spin. Even if you move it to a place where there is no air, the object will still spin because it has inertia. Inertia is the property of an object that causes it to resist changes in its state of motion. This means that an object will continue to move in a straight line or spin in a circle until it is acted on by an outside force.

Now that we know about inertia, let’s take a look at how it affects a rotating object. When you rotate an object about a fixed axis, the object will spin faster or slower depending on its mass. The more mass an object has, the more inertia it has. This means that the object will resist changes in its state of motion more than a lightweight object.

Another thing to consider is the location of the axis of rotation. If the axis is located near the object’s center of mass, the object will spin faster. If the axis is located near the object’s edge, the object will spin slower.

Now that we know how rotation affects an object, let’s take a look at how it affects a rigid body. A rigid body is an object that doesn’t deform when it’s rotated. This means that the object will keep its shape even when it’s spinning.

When you rotate a rigid body about a fixed axis, the object will spin faster or slower depending on its mass and the location of the axis of rotation. The object will also rotate more or less depending on its shape. If the object is symmetrical, it will rotate evenly about the axis of rotation. If the object is not symmetrical, it will rotate unevenly about the axis of rotation.

Now that you know about the effects of rotation on a rigid body, let’s take a look at some examples.

The first example is a rotating disk. When you rotate the disk, the object will spin faster or slower depending on its mass and the location of the axis of rotation. The disk will also rotate more or less depending on its shape. If the disk is symmetrical, it will rotate evenly about the axis of rotation. If the disk is not symmetrical, it will rotate unevenly about the axis of rotation.

The second example is a rotating cylinder. When you rotate the cylinder, the object will spin faster or slower depending on its mass and the location of the axis of rotation. The object will also rotate more or less depending on its shape. If the object is symmetrical, it will rotate evenly about the axis of rotation. If the object is not symmetrical, it will rotate unevenly about the axis of rotation.

The third example is a rotating cone. When you rotate the cone, the object will spin faster or slower depending on its mass and the location of the axis of rotation. The object will also rotate more or less depending on its shape. If the object is symmetrical, it will rotate evenly about the axis of rotation. If the object is not symmetrical, it will rotate unevenly about the axis of rotation.

The fourth example is a rotating sphere. When you rotate the sphere, the object will spin faster or slower depending on its mass and the location

## When a body or particle rotates about a fixed axis?

When a body or particle rotates about a fixed axis, it undergoes rotational motion. This occurs when the object rotates around a fixed point or line. The object will rotate at a constant speed, and the direction of the rotation will be the same as the direction of the axis.

There are three types of rotational motion: uniform, non-uniform, and combined. In uniform rotational motion, the object rotates at the same speed around the axis. In non-uniform rotational motion, the speed of the object changes as it rotates. In combined rotational motion, the object combines both uniform and non-uniform motion.

The rotational inertia of an object is the measure of the object’s resistance to rotational motion. The rotational inertia is determined by the object’s mass and its geometry. An object with a large rotational inertia will resist rotational motion more than an object with a small rotational inertia.

When a force is applied to an object in rotational motion, it will cause the object to accelerate. The amount of acceleration will depend on the size of the force and the rotational inertia of the object.

Rotational motion is an important concept in physics, and it is used to explain many phenomena in the natural world. It is important to understand the different types of rotational motion, and how to calculate the rotational inertia of an object.

## When a rigid body is in the rotational motion all points of the body have the same?

There are many physical phenomena that we experience in our everyday lives, but often do not take the time to question why they occur. One such example is when a rigid body is in rotational motion. All points of the body have the same angular velocity, and this is what causes the body to rotate as a whole.

To understand why this is the case, let’s consider a simple example. Suppose you have a rigid body consisting of a metal rod, and you want to rotate it about one of its ends. If you try to rotate it using only the end opposite the one you are gripping, you will find that it is very difficult to do so. In fact, even if you use a lot of force, you will only be able to rotate it a very small amount.

However, if you grip the rod near the end you are rotating, it is much easier to do so. In fact, you can rotate it through a much larger angle with very little effort. This is because when you are gripping the rod near the end you are rotating, you are providing a rotational force that is perpendicular to the rod. This force is what causes the body to rotate.

Now let’s consider what would happen if you tried to rotate the rod using only the end opposite the one you are gripping. In this case, you would be providing a force that is parallel to the rod. This force would not cause the body to rotate, and in fact would only cause the rod to move along its length.

So why is it that all points of a rigid body in rotational motion have the same angular velocity? It is because the force that is causing the body to rotate is perpendicular to the body. This means that the force is acting through the centre of mass of the body, and is therefore providing the same rotational force to all points of the body.

## When axis of rotation is fixed angular velocity is considered as?

When an object rotates around a fixed axis, its angular velocity is constant. This is because the object’s velocity is perpendicular to the axis of rotation. If the object were to move along the axis, its angular velocity would change, but because it is fixed in place, its angular velocity remains constant.

## When axis of rotation is fixed then angular velocity is considered as?

When an object rotates around an axis, the angular velocity is the rate at which it rotates. This velocity is measured in terms of the angle turned per unit time. The angular velocity is constant when the axis of rotation is fixed. If the axis of rotation is not fixed, then the angular velocity changes as the object moves.
