When a moving object is slowing down, i.e. its speed is decreasing.

Can acceleration ever be negative?

Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.


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.


If velocity is positive which would most likely yield a negative acceleration?

If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.


Does acceleration have a negative or positive value if the velocity is increasing speed?

In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)


Can an object have both negative velocity and acceleration?

Yes, an object can have negative velocity and negative acceleration if it is moving in the opposite direction of the positive axis. This would mean the object is both moving backwards and its speed is decreasing.


What happens to your speed if you have a negative acceleration do you speed up or slow down?

If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.


How would a graph of negative and positive acceleration differ?

This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).


A plane taking off is a negative acceleration?

A plane landing is a negative acceleration - "negative" meaning it slows down.


What is positive acceleration negative acceleration?

Positive is speeding up and negative is slowing down


True or false Negative acceleration always means that a system is slowing down?

false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
