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 a positive or negative value mean in physics?
In physics, a positive value typically indicates a quantity that is greater than zero, while a negative value indicates a quantity that is less than zero. Positive and negative values can represent different physical properties, such as direction, charge, energy, or force, depending on the context in which they are used.
Can instantaneous speed be negative?
No, instantaneous speed cannot be negative. Speed is a scalar quantity and is always positive or zero. Negative values can be associated with velocity, which is a vector quantity and can be negative if an object changes direction.
What is negative vector in physics?
In physics, a negative vector is a vector that points in the opposite direction to a positive vector of the same magnitude. Negative vectors are used to represent quantities or forces that act in the opposite direction within a specific coordinate system.
What does a stand for in physics?
In physics, "a" typically stands for acceleration, which represents the rate of change of velocity of an object over time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
What does trough mean in physics?
The trough in physics refers to the lowest point in a wave, where the displacement of the wave is at its maximum negative value. It is the opposite of the crest, which is the highest point in a wave where the displacement is at its maximum positive value. Together, the trough and crest form the waveform of a periodic wave.
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.
What does a positive or negative value mean in physics?
In physics, a positive value typically indicates a quantity that is greater than zero, while a negative value indicates a quantity that is less than zero. Positive and negative values can represent different physical properties, such as direction, charge, energy, or force, depending on the context in which they are used.
Where can you get positive and negative wires for a class project?
You can get the positive and negative wires for a class project at a store that sells the Physics apparatus.
What does negative answer mean?
its negative! negative reply, answer that is not positive
Do withdrew mean positive or negative?
positive
Can the sample mean in statistics be either positive or negative?
It can have either a negative or positive trend
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
What is a negative mean?
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
Can instantaneous speed be negative?
No, instantaneous speed cannot be negative. Speed is a scalar quantity and is always positive or zero. Negative values can be associated with velocity, which is a vector quantity and can be negative if an object changes direction.
A negative plus a positive equels?
A negative or a positive! It depends on the question.EXAMPLES-7 + 3 = -4 ( a negative answer)-7 + 8 = 1 (a positive answer)IF you mean a negative times a positive, the answer is negative:-3 x 5 = -15
What is the different between positive and negative decibel?
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
What does positive and negative effects mean?
A positive effect is one that is favorable; a negative effect is one that is unfavorable.
