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.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
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.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
What would a negative acceleration tell you about the object in motion?
the car is at a constant speed---------------------------------------------------------I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).
Why is it that their is an acceleration when a car is moving?
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
When a car slows down is it accelerating?
Yes. Acceleration is any change in velocity. When a car slows down it is decelerating; think of deceleration as acceleration in the negative direction.
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
By convention, yes, but the acceleration is negative
When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.
