That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
The bending of waves due to a change in speed is called refraction. This occurs when waves pass through different mediums with varying densities, causing the wave to change direction.
Any action that is able to change the motion of a body is called a force. Forces can cause objects to accelerate, decelerate, change direction, or deform.
A sudden change in wind speed and direction is called a wind gust. Wind gusts are short bursts of strong wind that can occur during thunderstorms, frontal passages, or other weather systems.
it can kill people and destroy houses
Light that appears to bend is called refraction. This occurs when light passes from one medium to another, causing a change in its speed and direction.
A change in position in a certain amount of time is called motion.
The speed is v and the starting speed is v0.
I'm uncertain about what you are seeking here. The change in an objects speed divided by the time required to change the speed would be the average acceleration.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
The change in an objects position is called motion.
Subsonic
Instantaneous Speed.
The study of speed is called kinetics. It involves analyzing the motion of objects and the factors that affect their speed.
Speed and direction is called velocity.
The tendency for objects to resist a change in their state of motion is called inertia.
The resistance to a change in velocity is called "inertia". It is related to the mass of an object.
Terminal velocity if it has reached its top speed. Or obviously constant speed.
