Weight is a force which is a vector and has a magnitude and direction. Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity.
Why is voltage not a vector?
Voltage is a scalar and electric field is a vector. Hint: This question is simply asking us to differentiate between a scalar and a vector quantity. A scalar quantity has a magnitude only but no direction which means this quantity is not biased to move in a particular direction.
Is vector math or physics?
A vector is defined as a mathematical structure. It has many applications in the field of physics and geometry. We know that the location of the points on the coordinate plane can be represented using the ordered pair such as (x, y).
Is mass a scalar?
We know that a scalar quantity is a quantity that contains only magnitude and no direction. Hence, mass is a scalar quantity.

Are watts a vector quantity?
Watt cannot be signified as any quantity bit as an unit of power. Power is a scalar quantity as it only depends on the magnitude and not the direction of the force applied.
Why is velocity a vector?
Velocity is displacement per unit time and has a specific direction. It contains direction as well as magnitude of a moving object, so velocity is a vector quantity.

Why we Cannot use DC?
With the help of a transformer, AC can be easily stepped up or down, but this is not possible in the case of DC current. DC current cannot be used in long circuits as it starts to lose energy. The direction of the DC current cannot be reversed.
Why we Cannot use DC current?
DC current is not used in homes because of the following reasons: First of all, DC is difficult to generate because primarily it is generated by batteries and electrochemical of photovoltaic cells. Power loss during transmission is more in direct current as compared to alternating current.
Can DC be inductive?
Direct currents don't cause much inductive action. When a switch is thrown and current first flows in a DC circuit, a magnetic field builds up. The field can induce a current to flow in any nearby wire, but only briefly, just during the few instants it takes for the current to get moving.
Is Dry Cell AC or DC?
Dry cells produces direct current .

Can an electric current be positive?
Since current can be the flow of either positive or negative charges, or both, a convention is needed for the direction of current that is independent of the type of charge carriers.
Can current flow through a capacitor?

Is electric current a scalar or a vector?
Electric current is a scalar quantity. Any physical quantity is defined as a vector quantity when the quantity has both magnitude and direction but there are some other factors which show that electric current is a scalar quantity .

Is Impulse a vector?
Impulse is a vector, so a negative impulse means the net force is in the negative direction. Likewise, a positive impulse means the net force is in the positive direction. People mistake impulse with work. Both impulse and work depend on the external net force, but they are different quantities.
Is time a distance or vector?
"Time" itself isn't a vector, just like position isn't a vector. You can give time a direction when talking about "elapsed time", or the difference between two points in time. This would be a vector quantity.
Is electric current a vector quantity Why?
It represents the direction of flow of positive charge but it is treated as a scalar quantity because current follows the laws of scalar addition and not the laws of vector addition, because the angle between the wires carrying current does not effect the total current in the circuit.
