When you change your straight-line velocity (speed) from slow to fast you have positive acceleration and from fast to slow it will be negative acceleration.

Acceleration = velocity change divided by time taken.

So when you are traveling at say 10 m/s and decelerate to zero in 5 seconds, your (negative) acceleration will be = (0-10)/5 = - 2 metres per sec per sec.

Normally expressed as -2m/s^2.

Q: Does acceleration happen when your stopping?

Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.

Acceleration is a net force that is inversely dependent on mass, therefore if an object mass increases ,acceleration decreases

if there unequal velocities in equal intervals of time.

The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.

the acceleration decreases

Acceleration becomes zero.

acceleration doubles too.

when there is change of speed

Reteradation will be half of acceleration

yes

It is acceleration in the horizontal direction. This would happen as a result of a net horizontal force acting on a body.
