Scalars are a magnitude by itself. Vectors are magnitude and direction.

Does acceleration have a magnitude only?

No, acceleration has both magnitude and direction. Magnitude refers to the rate of change of an object's velocity, while direction specifies which way the object is accelerating.


Is mass a vector or scalars?

Mass is a scalar value. Scalar refers to the magnitude of the object. Vector refers to the direction. If an object is moving, it's mass is scalar and its velocity is vectorial because the velocity has a magnitude (how fast) and a direction. Hope this helps. Search Scalar and vector for the true scientific definitions.


Does speed have magnitude only?

No, speed is a scalar quantity that only has magnitude and no direction. It is the rate at which an object covers distance. Velocity, on the other hand, is a vector quantity that includes both magnitude and direction.


What are the different derived quantities?

Scalar and vector quantities. Scalar quantities only have magnitude, like the volume of an object. Vectors have both magnitude and direction, like the velocity of an object.


What is the Speed is the magnitude?

Speed is the magnitude of an object's velocity, which is the rate of change of its position in a specific direction. It is a scalar quantity, meaning it only has magnitude and no specific direction associated with it.


Is distance a vector or scalar quantity?

Distance is a sclar quantity. A scalar quantity is a magnitude only. A vector has magnitude and direction. Distance AND direction is a vector quantity.


How is speed described?

Speed is a measure of how fast an object is moving. It is typically calculated as the distance traveled by an object in a specific amount of time. Speed is a scalar quantity, meaning it only has magnitude and no direction associated with it.


Is 51 Pegasi visible to the naked eye?

Yes, but only if the conditions are right. 51 Pegasi has an apparent magnitude [See Link] of 5.49. The faintest object the naked eye can see, has an apparent magnitude of 6.5 (in perfect conditions). Even with binoculars, the faintest object is 9.5. The larger the apparent magnitude, the dimmer the object is. Our Sun has an apparent magnitude of -26.73 (yes minus)


Why weight is a scalar?

Weight is a scalar because it only has a magnitude (amount) and no specific direction. It is a measure of the force of gravity acting on an object, defined as the mass of the object multiplied by the acceleration due to gravity. Since it only requires a magnitude to describe it, weight is considered a scalar quantity.


What would happen if there was only one force on an object?

If there is only one force acting on an object, the object will accelerate in the direction of that force according to Newton's second law of motion (F=ma). The acceleration will depend on the magnitude and direction of the force and the mass of the object.


Explain how velocity differs from speed?

Velocity includes not only the speed of an object but also its direction of motion. Speed is scalar quantity, meaning it only considers magnitude, while velocity is a vector quantity that requires both magnitude and direction.


A star of magnitude plus 8 is?

A star with a magnitude of +8 is "very dim", and not visible in urban or suburban areas. Only in the darkest rural areas, and only for people with EXCELLENT eyes, would a +8 magnitude star be visible.
