1. What is Dimensional Formula of Force?

Definition: The dimensional formula of force represents its physical quantities in terms of fundamental dimensions: mass (M), length (L), and time (T).

Purpose: It helps in understanding the relationship between different physical quantities and in verifying the correctness of physical equations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Force (Newtons)
• \( m \) — Mass (kilograms)
• \( l \) — Length (meters)
• \( t \) — Time (seconds)

Explanation: The dimensional formula [M][L][T⁻²] shows that force depends on mass, length, and inverse square of time.

3. Importance of Dimensional Analysis

Details: Dimensional analysis helps verify equations, convert units, and understand physical relationships. The dimensional formula of force is fundamental in physics.

4. Using the Calculator

Tips: Enter mass in kg, length in meters, and time in seconds. The calculator will compute the force in Newtons and display its dimensional formula.

5. Frequently Asked Questions (FAQ)

Q1: Why is the dimensional formula important?
A: It helps check the consistency of physical equations and understand the relationship between different physical quantities.

Q2: What are the units of force?
A: In SI units, force is measured in Newtons (N), where 1 N = 1 kg·m/s².

Q3: How is this related to Newton's Second Law?
A: Newton's Second Law (F=ma) directly gives us the dimensional formula since acceleration has dimensions [L][T⁻²].

Q4: Can I use this for other force calculations?
A: Yes, this dimensional formula applies to all types of forces (gravitational, electromagnetic, etc.) as long as they follow Newton's laws.

Q5: What about other systems of units?
A: The dimensional formula remains the same, but the numerical value will change based on the unit system used.
