What does it mean if velocity is negative in a physical context?
In a physical context, a negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
Is it possible for velocity to be negative?
Yes, velocity can be negative. Negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
What does the negative portion of a velocity vs time graph mean?
A negative portion of a velocity vs time graph indicates that the object is moving in the negative direction relative to a chosen reference point. The slope of the graph during the negative portion represents the magnitude of the velocity in the negative direction.
Does a negative acceleration always mean a decrease in speed?
Not necessarily. Negative acceleration indicates a decrease in velocity, which can either mean a decrease in speed or a change in direction depending on the initial velocity and the direction of the acceleration.
Is it possible for a velocity to be negative?
Yes, it is possible for velocity to be negative. Negative velocity indicates that an object is moving in the opposite direction of its positive velocity.

Is it possible for velocity to be negative?
Yes, velocity can be negative. Negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
What does the negative portion of a velocity vs time graph mean?
A negative portion of a velocity vs time graph indicates that the object is moving in the negative direction relative to a chosen reference point. The slope of the graph during the negative portion represents the magnitude of the velocity in the negative direction.

Not necessarily. Negative acceleration indicates a decrease in velocity, which can either mean a decrease in speed or a change in direction depending on the initial velocity and the direction of the acceleration.
Is it possible for a velocity to be negative?
Yes, it is possible for velocity to be negative. Negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
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.
Can you have a negative velocity followed by south?
What I mean is can you have a negative velocity followed by "south". (i.e. -7.5 m/s south) or would the velocity be 7.5 m/s south? My opinion is that the negative sign is not necessary since south is already "negative" so you would be canceling out the negative if you have the sign making it 7.5 m/s north.
When is acceleration neg?
Acceleration is negative if velocity is decreasing with time. Since velocity is a vector this can occur in one of two ways: 1) you are slowing down in the direction of motion and the velocity in that direction is defined as positive (this is what we usually mean by negative acceleration) 2) you are speeding up in the direction of motion and the velocity in that direction is defined as negative. An example of this is an object launched into the air which immediately starts to decelerate in it's upward velocity, reaches it's highest velocity, and then begins accelerating towards the ground. If we call the velocity upward a positive velocity, then when it starts falling, it has negative velocity. Note that acceleration (due to gravity) is negative the whole time.
What does velocity slope mean?
Velocity slope refers to the rate at which velocity changes over time. A positive velocity slope indicates an increase in velocity, while a negative velocity slope indicates a decrease in velocity. The steeper the slope, the greater the rate of change in velocity.
What is the physical meaning of a negative average velocity?
A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
