1. What is Newton's Second Law?

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. The formula is expressed as F = m × a.

2. How Does the Calculator Work?

The calculator uses Newton's Second Law formula:

Where:

• \( F \) — Force (Newtons)
• \( m \) — Mass (kilograms)
• \( a \) — Acceleration (meters per second squared)

Explanation: The force acting on an object equals the mass of the object multiplied by its acceleration.

3. Importance of Force Calculation

Details: Calculating force is fundamental in physics and engineering for understanding motion, designing structures, and analyzing mechanical systems.

4. Using the Calculator

Tips: Enter mass in kilograms and acceleration in m/s². Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the SI units for force?
A: The SI unit for force is the Newton (N), which equals 1 kg·m/s².

Q2: Can this formula be used for any type of force?
A: Yes, Newton's Second Law applies to all types of forces including gravitational, frictional, and applied forces.

Q3: What if acceleration is zero?
A: If acceleration is zero, the net force acting on the object is also zero (according to Newton's First Law).

Q4: Does this law apply to rotating objects?
A: For rotating objects, the rotational equivalent is τ = I × α, where τ is torque, I is moment of inertia, and α is angular acceleration.

Q5: How is this different from Newton's First Law?
A: Newton's First Law describes inertia (objects at rest stay at rest, objects in motion stay in motion), while the Second Law quantifies how force affects motion.
