What properties of a scalar quantity?
They only have a magnitude , no direction.
Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
What has magnitude only?
Magnitude refers to the size or quantity of something without direction. Examples of things that have magnitude only include scalar quantities like speed, temperature, and energy. These values are not associated with a specific direction but rather represent a numerical value.
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
What two pieces of information are necessary in order to define vector quantity?
To define a vector quantity, you need both magnitude (the numerical value) and direction. This combination of magnitude and direction is what distinguishes vector quantities from scalar quantities, which only have magnitude.

Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
Which one of these is a scalar value?
A scalar value is a single value that represents a magnitude only, without a direction. Examples include temperature, mass, distance, and time.
What is the absolute value of -7.61?
Absolute value of any number is just the magnitude without any sign attached to it. For positive numbers the magnitude is the value of the number. For negative numbers just remove the negative sign and you will have the magnitude. In this case the magnitude is 7.61
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
How are Speed and acceleration related?
Speed is a scalar value meaning it has only a magnitude and velocity is a vector value meaning it has magnitude and a direction. The magnitude could be speed but if you say, "I'm going 3 meters per second," then you would be talking about speed but if you said, "I'm going 3 meters per second west," then you would be talking about velocity and a vector value. An acceleration is just a change in the magnitude and/or direction of a velocity.
Which acceleration has larger magnitude?
The acceleration with the larger magnitude is the one with a greater numerical value, regardless of its direction. Acceleration is a vector quantity, meaning it has both magnitude and direction, but when comparing magnitudes, only the numerical values are considered.
What two pieces of information are necessary in order to define vector quantity?
To define a vector quantity, you need both magnitude (the numerical value) and direction. This combination of magnitude and direction is what distinguishes vector quantities from scalar quantities, which only have magnitude.
Can Distance be fully described with a magnitude and a unit?
Distance can be fully described with a magnitude and a unit. It is a scalar quantity, which means it has a magnitude (numerical value) but not a direction. A related quantity is displacement, which is the straight line distance from a starting point to an ending point. Displacement is a vector quantity, so it can only be fully described with a magnitude, a unit, and and direction.
How do you use scalar in a sentence?
In physics, a scalar is a quantity that has only magnitude, without a direction. For example, temperature is a scalar quantity because it only has a value (e.g., 25 degrees) without needing a direction.
