I believe it's velocity or momentum.
The speed of an object at a specific moment in time is called instantaneous speed.
It is called "speed." If the direction is also included, the measurement is "velocity."
Speed. The equation to find speed is distance over time.
The speed and direction of an object is called its velocity. Velocity is a vector quantity that includes both the magnitude (speed) and the direction of motion.
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".
The speed at a given point is called instantaneous speed. It represents the speed of an object at a specific moment in time.
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
subsonic
the object's 'velocity'
The speed of an object at a particular moment in time is called instantaneous speed. It is the rate at which an object is moving at an individual point in time.
the object's "speed".(not 'velocity')
The linear speed of an object moving in a circle is called tangential speed. It represents how fast a point on the object's edge is moving along the circumference of the circle.
