Constant speed
Change in speed (more precisely change in velocity) is called acceleration.
A change in position in a certain amount of time is called motion.
The control, or constant.
It doesnt look like you can change the speed of your cell phone ring tone..you can however download another ringtone that would be a better speed. they are very affordable and there are several to choose from.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Speed.
It is called refraction.
The change in speed of light when traveling through different mediums is known as refraction. Refraction occurs because light waves change speed as they pass from one medium to another, causing them to bend.
That is called acceleration.
Acceleration.
No, speed can vary and one can still calculate the average speed of an entire trip. Average speed is equal to the change in distance divided by the change in time.
