Speed plus the direction of travel.
What else can I help you with?
Why does velocity represents rate of change of displacement?
Because that is the definition of velocity
What is the definition of deacceleration?
Decrease in of velocity
What is average velocity's definition?
Average Velocity is displacement over total time.
Can an object be accelerating if it has a constant velocity?
No. The definition of 'acceleratiion' is 'any change in velocity'.
Can an object acceleration if its velocity is constant?
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 momentum define?
what is the definition for momentum
What is the best definition of velocity?
The speed of something in a given direction.
Why does the unit of time appear twice in the definition of acceleration?
Once for the unit of velocity and again for the interval of time in which the velocity is changing.
Scientific definition of velocity?
The time derivative of displacement, dD/dt.
What is the speed and direction at which something moves?
That's the definition of its velocity vector.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
What does acceleration have to do with go karts?
Whenever a velocity changes, by definition you have an acceleration.
