What does it mean when velocity is negative?
When velocity is negative, it means that the object is moving in the opposite direction of its positive 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.
What does positive and negative mean in physics?
In physics, positive and negative typically refer to the direction of a physical quantity, such as velocity or charge. A positive value indicates a quantity is moving in one direction, while a negative value indicates movement in the opposite direction. It's a way to describe the orientation or polarity of a physical property.
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.
What does it mean when velocity is negative?
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.

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.
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 does 30- mean in math?
it could mean negative 30 derees, negative 30 etc. you would need the context
A negative slope on the velocity vs. time graph indicates that the object is not moving.?
False. It means it is slowing Down!
Is placid negative or positive?
It depends on the context. It may mean quiet, unruffled (positive) or it could mean too laid back to do anything (negative).
