Question

define dimensional variables and dimensional constants with example​

Answer 1

Answer:

Dimensional variables are those whose quantities which have dimensions and whose numerical value may change... ex:-speed, velocity, acceleration e.t.c...

Dimensional constants are quantities having dimensions but having a constant value,

ex:-gravitation constant (G), Planck constant (H).

Dimensional Constant:-

Those physical quantities having dimensional formula and a constant value are known as dimensional constants.

Ex:-

• Planck's constant (h)
• Gravitational constant (G)
• Universal gas constant (R)
• Velocity of light in vacuum (c)....etc.

Dimensional Variables:-

Those physical quantities having a dimensional formula and can have different values are known as dimensional variables.

Ex:-

• Velocity
• Acceleration
• Force
• Work ..etc.
