physics, chap2(scalar and vector quantities)

What is a scalar quantity?

A physical quantity that can be specified completely by its magnitude alone.

List examples of scalar quantities.

Mass, density, energy, work, power, temperature, speed, quantity of heat, specific charge, electric power, resistance, frequency, etc.

How do scalar quantities follow algebra for their operations?

Scalar quantities can be added, subtracted, multiplied, and divided by simple arithmetic methods.

How are scalar quantities written symbolically?

They are written by their English letter.

What is a vector quantity?

A physical quantity that can be specified completely by its magnitude as well as direction.

List examples of vector quantities.

Displacement, velocity, acceleration, force, weight, momentum, moment of force, impulse, temperature gradient, electric field, magnetic field, etc.

How do vector quantities follow different algebra for their operations?

Vector quantities follow different algebra for their addition, subtraction, and multiplication.

How are vector quantities written symbolically?

They are symbolically written by their English letter with an arrow on top or by the bold English letter
