Speed plus the direction of travel.
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'.
Zero, by definition. "Terminal velocity" implies that the velocity no longer changes.
No, velocity is not based on weight. Velocity is a measure of how fast an object is moving in a particular direction, and it is determined by both the object's speed and the direction in which it is moving. Weight, on the other hand, is a measure of the force of gravity acting on an object due to its mass.
No. The definition of acceleration is change in velocity.
Velocity is the rate at which an object changes its position in a specific direction. It is a vector quantity that includes both the object's speed and the direction of its motion. Velocity is typically expressed in units of distance per time (e.g., meters per second).
Force
Velocity is a vector quantity that describes the rate at which an object changes its position. It includes both the speed of the object and the direction in which it is moving. Mathematically, velocity is defined as the rate of change of an object's position with respect to time.
The official definition for the word group velocity is "the speed at which the energy of a wave travels."
Absolute velocity is the velocity of an object with respect to a fixed point in space, regardless of the motion of other objects. It provides a consistent measure of an object's speed and direction in relation to a stationary frame of reference.
