the velocity of an object changes when it speeds up or slows down.
Acceleration is the change in velocity and/or direction of an object. Acceleration can either speed an object up, slow it down (deceleration), or change the direction in which the object is moving.
doing some homework? A net force vector/imbalance can either increase velocity (positive acceleration), decrease velocity (negative acceleration) or effect zero acceleration (perpendicular).
-- The speed can increase. -- The speed can decrease. -- The path can bend from a straight line. Each of these is an example of 'acceleration'.

To change density there are three ways. You can change the shape, mass or volume of the object
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.
Mass and velocity
It can only be accelerated or decelerated, by adding to, or deleting from, the applied force causing the motion, or by increasing or decreasing the (opposing) frictional force. Acceleration includes starting. Deceleration includes stopping. Directional change may be imposed without causing a change in velocity, although practically, this change would be difficult to accomplish.
