Overview

Force is an interaction that, when unopposed, will change the motion of an object. Newton's second law (F = ma) states that the force acting on an object is equal to its mass multiplied by its acceleration. This fundamental relationship governs all motion in classical physics.

💡

Pro Tips

The standard unit of force is the Newton (N), where 1N = 1kg⋅m/s².
Force is a vector quantity with both magnitude and direction.
In the absence of net force, an object will maintain constant velocity (including zero velocity).
The weight of an object is a force: W = mg (mass × gravity).

Fun Facts

"The 'Newton' was named after Sir Isaac Newton, who formulated the laws of motion in 1687."
"A single sheet of paper has a mass of about 5 grams, yet it takes significant force to crumple it!"
"The strongest force in the universe is the strong nuclear force, billions of times stronger than gravity."
"Your heartbeat creates enough force to squirt blood 30 feet if arteries were straight tubes."

Formula: F = m × a
