the velocity of an object changes when it speeds up or slows down.
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
The velocity of a car can change by increasing its speed, such as accelerating when pressing the gas pedal, or by decreasing its speed, such as decelerating when applying the brakes.
Any acceleration.Acceleration in physics is classed as loss or gain or speed, or any change in direction.
Two ways: If the change in velocity is the result of hitting something, use the Momentum Equation. If the change in velocity is the result of applying a force, use the Impulse Equation. You probably mean this equation, which is: FT = m(Vf - Vo) Or, An object of mass "m" will change from velocity "Vo" to velocity "Vf" if the force "F" is applied for "T" seconds.
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
speed and direction
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
changes in speed or direction or both
The velocity of a car can change by increasing its speed, such as accelerating when pressing the gas pedal, or by decreasing its speed, such as decelerating when applying the brakes.
You change momentum by changing mass or, more commonly, velocity.
Any acceleration.Acceleration in physics is classed as loss or gain or speed, or any change in direction.
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).

Velocity changes when the direction of the motion changes.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
The range of change of velocity is determined by the final velocity minus the initial velocity. It represents the magnitude and direction of the change in velocity of an object.
