If a rock is whirling around by a string and the string is allowed to increase in length what is the effect on the rotational speed of the rock?
Let us bring in a little bit of physics shall we just to make it interesting. Because of air trying to resist the speed of the rock we would have to increase our rotaion for the rock to remain at its original speed as the string is let out. Now for the physics bit. If there were no air to impeed the rock its speed would remain constant no matter how long the string. Actually, Newtons first law of motion comes into the picture here but he talks of an object travelling in a stright line, however the principle is the same.

What are the factors that affect an objects rotational kinetic energy?
An object's rotational kinetic energy is affected by its moment of inertia (how mass is distributed around its axis of rotation), its angular velocity (how fast it is rotating), and its mass. Increasing any of these factors will increase the object's rotational kinetic energy.
What is the rotational analog f mass?
The rotational analog of mass is moment of inertia. It represents the resistance of an object to change in its rotational motion and depends on the distribution of mass around the axis of rotation.
What is difference between rotational and revolutionary motion?
Rotational motion occurs when an object spins or rotates around a fixed axis, like a spinning top. Revolutionary motion occurs when an object moves around another object, like a planet orbiting around a star. Essentially, rotational motion involves spinning in place, while revolutionary motion involves moving around another object in a circular path.
What role does torque play in the rotational motion of machines?
Torque is the rotational equivalent of force, responsible for causing an object to rotate around an axis. In machines, torque is pivotal for providing the necessary power to drive the rotational motion of components like shafts, gears, and pulleys. The magnitude of torque determines the acceleration or deceleration of rotational motion in machines.
How can rotational balance be achieved in a system or object?
Rotational balance in a system or object can be achieved by ensuring that the center of mass is evenly distributed around the axis of rotation. This can be done by adjusting the distribution of mass or by adding counterweights to balance out any uneven weight distribution. Additionally, ensuring that the rotational forces are equal and opposite can help maintain rotational balance.
What does whirly dirvy mean?
Shortened from the 'Whirling Dervish'. The Whirling Dervishes are a sect of Islam taught to love everything. They spin around and around as a form of meditation.
Can whirling disease affect betta fish?
Whirling disease is unlikely to cause damage to Bettas if they are kept at the proper temperature of around 75F.
What are the factors that affect an objects rotational kinetic energy?
An object's rotational kinetic energy is affected by its moment of inertia (how mass is distributed around its axis of rotation), its angular velocity (how fast it is rotating), and its mass. Increasing any of these factors will increase the object's rotational kinetic energy.
What is whirling hygromwter?
A whirling hygrometer is a device used to measure humidity in the air. It consists of two thermometers, one of which has a wet bulb and the other a dry bulb. By swinging or whirling the device around, the evaporation of water from the wet bulb creates a cooling effect, allowing for the calculation of relative humidity.
What year does whirling devishes originate from?
The whirling dervishes is an Islamic way of dance to represent the treating of the ill healthed which originated in the 20th Century and is more prominent in the modern day around the area of Turkey as there are festivals connected to it
What is rotational analog?
The rotational analog is 2nd of newtons law it is the angular acceleration of a rigid object around an axis is proportional to the next external torque on the body around its axis and inversely proportional to the moment of rotational inertia about that axis.
What is the rotational analog f mass?
The rotational analog of mass is moment of inertia. It represents the resistance of an object to change in its rotational motion and depends on the distribution of mass around the axis of rotation.
Why do the hours of daylight increase in the summer?
The earths rotational axis is tilted approx. 23 degrees from vertical The earths rotational axis remains parallel throughout its rotation around the sun, high summer (longest day) in the northern hemisphere, is when the top of the axis is at full tilt toward the sun. (shortest day in the southern hemisphere)
How many degrees rotational symmetry for a pinwheel?
right around 400,00
How do you use rotational symmetry in a sentence?
When an image, from a point, can be turned around a certain number of degrees and continue to look the same, it can be said the image has rotational symmetry.
What is Andromedas rotational period?
what is Saturn's moon Titan's rotational period
Why do puppies hump stuffed animals?
Because they have nothing else to do and if they have lots of hormones whirling around inside then they've gotta let them out somehow
