Velocity is the speed of an object.
Acceleration is the rate of change of velocity with respect to time. It describes how quickly an object's speed or direction is changing. Mathematically, acceleration is the derivative of velocity with respect to time.
Wave velocity is the speed at which a wave travels through a medium. It is determined by the frequency and wavelength of the wave, following the equation velocity = frequency x wavelength.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
No. The definition of acceleration is change in velocity.
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
Because that is the definition of velocity
Decrease in of velocity
Average Velocity is displacement over total time.
No. The definition of 'acceleratiion' is 'any change in velocity'.
Speed plus the direction of travel.
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
what is the definition for momentum
The speed of something in a given direction.
Once for the unit of velocity and again for the interval of time in which the velocity is changing.
The time derivative of displacement, dD/dt.
That's the definition of its velocity vector.
Zero, by definition.
