If an object's speed changes, or it heads off in a new direction, its velocity has changed.
Because of friction and gravity
1. acceleration
2. deceleration
3. change of 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).
The variably of velocity can be increased or decreased by altering other factors. The removal or reduction of air resistance can result in higher velocity (if force is held constant). If force is increased velocity can also become higher. Reduction of mass and varying gear ratios can also correspond to higher velocity.
The three ways are: radiation, conduction, and convection.
Either it is at Rest or Moving with Constant Velocity/Speed.

speed and direction
The gas pedal, the brake pedal, and the steering wheel all do.
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.
the velocity of an object changes when it speeds up or slows down.
You change momentum by changing mass or, more commonly, velocity.
doing some homework? A net force vector/imbalance can either increase velocity (positive acceleration), decrease velocity (negative acceleration) or effect zero acceleration (perpendicular).
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).
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.
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
