What is Force in Physics?
In classical Newtonian mechanics, force is any push or pull that alters or has the tendency to alter the motion of an object (F = ma). The SI standard unit is the Newton (N), defined as the force required to accelerate 1 kilogram of mass at 1 meter per second squared ($1 ext{ N} = 1 ext{ kg}cdot ext{m/s}^2$).
Frequently Asked Questions
How many Newtons equal 1 pound-force?
1 lbf equals exactly 4.44822 Newtons. To convert from lbf to Newtons, multiply by 4.44822.
What does 1 Kilonewton (kN) feel like?
1 kN equals 1,000 Newtons, which corresponds to the downward gravitational weight of approximately 102 kilograms (225 pounds) on Earth.
