A turntable is rotating at an angular velocity of {eq}4\pi {/eq} rad/s. How long does it take for it to complete one revolution? Angular Velocity: The below expression shows the angular velocity of an object if it is following a circu...
Galaxies are large systems of stars, gas, dust and dark matter that orbits a center and is bound by gravity. Learn about the characteristics of galaxies.
The blue is the actual velocity during this time, and the green is the estimated velocity. Notice how the green waveform is always above the blue waveform. In general this is always true, due to the backward-looking property of any real algorithm: when velocity is decreasing, any estimate o...
axis of rotation, and linear circular velocity, which is not, is that two people experiencing the same ω may be undergoing vastly different physical experiences. If you happen to be 1 meter from the center if this putative, massive merry-go-round, your linear (tangential) velocity ...
where u⃗u→ is the velocity of the moving conductor and the integral is done over the conductor path. As you see, for the whole rotating circle, the cross product is done between the velocity which is tangent to the circle and the magnetic field which is normal to...
(like a circular orbit). if it is moving with a constant speed in a circle, the magnitude of the change in vector momentum would be: r is the radius of the circle. if you like to look at this in terms of the speed of the object, v is the magnitude of the velocity. or maybe ...
Damien has a master's degree in physics and has taught physics lab to college students. Cite this lesson Angular velocity and linear velocity are the two types of object velocity. Learn how to find the angular velocity of an object and understand how to convert it to linear velocity. Cre...
The equation for kinetic energy is KE = 1/2mv^2, where m is the mass of the object and v is the velocity or speed of the object. 2. How does kinetic energy relate to an object's motion? Kinetic energy is the energy an object possesses due to its motion. The faster an object is...

Simulations of clusters with orbits like Gaia 1 find that they are stripped of stars and dispersed by these high velocity 'plane passages'. That puts it at odds with the age estimate. "Our finding that Gaia 1 is three billion years old is curious as the models would have it not surviving...
