The equation is F = M A, where F is the Force required to stop the object, M is the object's Mass, and A is its Acceleration. Note that its acceleration in this case is the rate at which you are DE-ACCELERATING the object to stop it.

Acceleration is zero when the object's speed and direction stop changing.
When the car is coming to a stop, it is decelerating--or it has negative acceleration.
If there is no net force on an object, the object won't accelerate.
A force or acceleration
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
Maybe your car sucks.

AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
