Force Formula:
From: | To: |
Definition: Force is a physical quantity that describes the interaction between objects, calculated as the product of mass and acceleration.
Purpose: This calculator helps determine the force exerted when a mass is subject to acceleration, according to Newton's Second Law of Motion.
The calculator uses the formula:
Where:
Explanation: The force required to accelerate an object is directly proportional to both the mass of the object and the acceleration.
Details: Understanding force is fundamental in physics, engineering, and everyday applications from vehicle safety to construction.
Tips: Enter the mass in kilograms and acceleration in m/s². All values must be > 0.
Q1: What is a Newton?
A: One Newton (N) is the force needed to accelerate 1 kg of mass at 1 m/s².
Q2: How does gravity relate to this formula?
A: On Earth, gravitational acceleration is ~9.81 m/s², so weight (force due to gravity) = mass × 9.81.
Q3: Can this calculate deceleration?
A: Yes, use negative acceleration values for deceleration (though this calculator requires positive inputs).
Q4: What if I know force and need to find mass or acceleration?
A: Rearrange the formula: m = F/a or a = F/m.
Q5: Does this work for rotational motion?
A: Rotational motion uses torque (τ = I × α), which is analogous but different units.
