Yes. The energy from the work you do can be wasted due to friction. But in such a case, it still requires work to rotate an object - since you are applying force, and you are applying it over a certain distance.
The work done by torque in rotating an object is the amount of energy transferred to the object to make it rotate. Torque is a force that causes an object to rotate around an axis, and the work done by torque is calculated by multiplying the torque applied to the object by the angle through which the object rotates.
It doesn't work like that. You don't need power to keep an object rotating. Any object that is rotating will continue rotating, unless it is slowed down, by friction for example.
There is energy in a rotating mass. Work equal to that energy has to be done on it to get it rotating. But it will keep on rotating without any additional work or energy, unless it is slowed down by friction, or other forces.
Radial acceleration and linear acceleration are related in a rotating object because radial acceleration is the acceleration towards the center of the circle due to the change in direction of velocity, while linear acceleration is the acceleration along the tangent to the circle due to the change in speed. In a rotating object, both types of acceleration work together to determine the overall motion of the object.
Any object that rotates has a tendency to continue rotating.
No. If you have three suns rotating around each other, that would mean that an object would have to be rotating around two other objects that are rotating around the other two objects, which is rotating around the two original objects. It just can't work
No, unless something makes it stop. It would take a tremendous amount of energy to make the rotation stop and then start again. There is a law of conservation of rotational momentum; a rotating object like the Earth can't simply stop rotating by itself, it would require an outside force to do that.
The angular velocity of a rotating object in a physics equation involving the keyword omega represents the rate at which the object is rotating around a fixed axis. It is denoted by the symbol omega () and is measured in radians per second.
The rotational potential energy formula is E 1/2 I 2, where E is the rotational potential energy, I is the moment of inertia of the object, and is the angular velocity of the object. This formula is used to calculate the energy stored in a rotating object by taking into account the object's moment of inertia and how fast it is rotating.
Angular acceleration and linear acceleration are related in a rotating object through the equation a r, where a is linear acceleration, r is the radius of the object, and is the angular acceleration. This equation shows that the linear acceleration of a point on a rotating object is directly proportional to the angular acceleration and the distance from the center of rotation.
The formula to calculate the angular velocity of a rotating object is angular velocity () change in angle () / change in time (t).
This question is similar to "How does linear motion function? With the exception of the planetary system, first it must be driven by power. When driven and no load applied to it, then its just an object in motion. In other words a motion without load or work whether it be rotation or linear motion does not serve a function.
