Force Calculator - Newton's Second Law

This physics calculator helps you calculate force using Newton's second law of motion. Force is a fundamental concept in physics that describes the interaction between objects and their environment.

Newton's Second Law

The force acting on an object is equal to the mass of the object multiplied by its acceleration:

F = ma

Force Units

• Newton (N): SI unit of force, 1 N = 1 kg⋅m/s²
• Dyne (dyn): CGS unit of force, 1 dyn = 1 g⋅cm/s²
• Pound-force (lbf): Imperial unit of force

Common Applications

• Weight: Force due to gravity (F = mg)
• Friction: Force opposing motion
• Tension: Force in ropes and cables
• Normal Force: Force from surfaces

Physics Concepts

• Mass: Amount of matter in an object (kg)
• Acceleration: Rate of change of velocity (m/s²)
• Force: Push or pull on an object (N)
• Net Force: Sum of all forces acting on an object
