Question 1

What is the formula for force?

Accepted Answer

Force is calculated using Newton's second law: F = m × a, where F is force in Newtons (N), m is mass in kilograms (kg), and a is acceleration in meters per second squared (m/s²).

Question 2

What is a Newton (N)?

Accepted Answer

One Newton is the force needed to accelerate 1 kilogram of mass at 1 meter per second squared. 1 N = 1 kg·m/s². For reference, 1 Newton ≈ 0.225 pounds of force.

Question 3

How do I calculate mass from force and acceleration?

Accepted Answer

Rearrange F = ma to solve for mass: m = F / a. For example, if a force of 50 N causes an acceleration of 10 m/s², the mass is 50/10 = 5 kg.

Question 4

What is the relationship between force, mass, and acceleration?

Accepted Answer

Force is directly proportional to both mass and acceleration. Doubling the mass doubles the force (at constant acceleration), and doubling the acceleration doubles the force (at constant mass).
