Is velocity a scalar or vector quantity?

Velocity is a vector quantity because its associated with both magnitude and direction.

What does scalar mean?

(of a quantity) having only magnitude, not direction.

Is acceleration a scalar or vector quantity?

Acceleration is a vector quantity because it has both magnitude and direction. When an object has a positive acceleration, the acceleration occurs in the same direction as the movement of the object.

What is the definition of direction?

Direction is a coarse along which something or some one moves.

Is displacement a scalar or vector quantity?

Displacement is a vector quantity because it needs a direction/it already has direction.

Is distance a scalar or vector quantity?

Distance is a scalar quantity because it lacks direction.

Is force a scalar or vector quantity?

Force is a vector and has a magnitude and direction.

What is the Magnitude and Direction in this scenario."I walked 25 m/s Eastward to get to the store"

Magnitude in this scenario is 5 meters per second because it tells you how far you were going. Direction in this scenario is Eastward because it tells you which way the person went.

What is the definition of magnitude?

Magnitude is the great size or extent of something.

Is mass a scalar or vector quantity?

Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity.`

What is the difference between scalar vs. vector quantities?

Scalar quantity: described by only a magnitude Vector quantity: described by both magnitude and direction.

Is speed a scalar or vector quantity?

Speed is a scalar quantity because its only associated with magnitude.

Is time a scalar or vector quantity?

Time clearly has no such direction

What does time mean?

a limited period or interval, as between two successive events: a long time.

What does vector mean?

a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.

What does distance mean?

an amount of space between two things or people.

What does acceleration mean?

increase in the rate or speed of something.

What does accuracy mean?

the quality or state of being correct or precise.

What does precision mean?

the quality, condition, or fact of being exact and accurate.
