... Uniform Circular Motion, UCM: moving in a circle with a constant speed. Question: Is there a constant velocity when an object moves in a circle with a constant speed? No, the direction changes, therefore the velocity changes. If the velocity changed, the object is actually ACCELERATING even while m ...

... A wire is made up of metal ions surrounded by a sea of free electrons which flow (a current) If the voltage increases, the temperature of a wire will increase. This will cause the ions to vibrate with higher amplitude and therefore increase the frequency of electrons colliding with the ions. This wo ...
