Force Formula:
From: | To: |
Definition: The equation F = ma represents Newton's second law of motion.
Purpose: It describes the relationship between an object's mass, acceleration, and the applied force.
The calculator uses the formula:
Where:
Explanation: The force acting on an object is equal to its mass multiplied by its acceleration.
Details: Understanding force calculations is essential in physics, engineering, and various practical applications from vehicle safety to structural design.
Tips: Enter the mass in kilograms and acceleration in m/s² (default 9.81 m/s² for Earth's gravity). All values must be > 0.
Q1: What is a Newton (N)?
A: A Newton is the SI unit of force. 1 N is the force needed to accelerate 1 kg at 1 m/s².
Q2: What's Earth's gravitational acceleration?
A: Approximately 9.81 m/s² at Earth's surface (varies slightly by location).
Q3: Can I calculate mass or acceleration instead?
A: Yes, you can rearrange the formula: m = F/a or a = F/m.
Q4: Does this work for rotational motion?
A: No, rotational motion uses torque (τ = Iα) where I is moment of inertia and α is angular acceleration.
Q5: How does air resistance affect this calculation?
A: Air resistance is an additional force that would need to be considered in real-world applications.
