Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.

It is physically impossible for an object to have a negative acceleration and yet be speeding up?
An object with a negative acceleration is slowing down, not speeding up. Negative acceleration means the object is decelerating or moving in the opposite direction of its velocity, causing it to slow down. Objects speed up when their acceleration is in the same direction as their velocity.
Can acceleration be a negative number?
Yes, acceleration can be a negative number. Negative acceleration means that the object is slowing down, or changing its velocity in the negative direction. It indicates a decrease in speed or a change in direction opposite to the initial motion.
Two words for what happens when an objects velocity decreases?
negative acceleration
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.

Yes, acceleration can be a negative number. Negative acceleration means that the object is slowing down, or changing its velocity in the negative direction. It indicates a decrease in speed or a change in direction opposite to the initial motion.
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
Two words for what happens when an objects velocity decreases?
negative acceleration
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Which magnitude is brighter a negative number or a positive number?
A positive number is brighter than a negative number. Brightness in astronomy is measured in magnitudes, where smaller (negative) magnitudes represent brighter objects. Positive magnitudes are assigned to dimmer objects.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
Which term explains whether an objects velocity has increased or decreaseed over time?
Acceleration describes whether an object's velocity has increased or decreased over time. An object has positive acceleration if its velocity is increasing, negative acceleration if its velocity is decreasing, and zero acceleration if its velocity is constant.
Both speed and acceleration include the direction of an objects motion?
Yes! In most problems direction needs to be defined as either positive or negative.
