Force Calculator
Calculate force using Newton's second law (F = ma). Enter mass and acceleration to get instant results in newtons, dynes, or pound-force.
Formula
F = m × a
Force equals mass multiplied by acceleration.
Worked Examples
Example 1: Falling Object
Problem:10kg object accelerating at 9.8m/s²
Solution:10 * 9.8
Result:98 N
Frequently Asked Questions
What is the unit of Force?
The standard unit of force is the Newton (N). 1 N = 1 kg·m/s².
Can force exist without motion?
Yes, forces can exist in static equilibrium (e.g., a book resting on a table has gravity pulling down and normal force pushing up).
What is a contact force?
A force that occurs when two objects are physically touching (e.g., friction, tension, normal force).
What is a field force?
A force that acts over a distance without physical contact (e.g., gravity, magnetism).
