What is the negative acceleration?
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
When final velocity is less then initial velocity of an object the acceleration is negative?
yes, many answers in applied maths come out as negative, it just means that the force or object is slowing down or reversing. in this case there is a negative acceleration as its slowing down
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
When an object's initial velocity is less than its final velocity what does that indicate?
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.
