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).
