Newton's second law states that force is proportional lớn what is required for an object of constant mass lớn change its velocity. This is equal lớn that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our mặc định units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second², etc.) could certainly be used as well - the calculation is the same regardless.

What is the force required lớn accelerate an object with a mass of đôi mươi kilogam from stationary lớn 3 m/s²?

F = m * a

F = đôi mươi kilogam * 3 m/s²

F = 60 N

Newtons are a derived unit, equal lớn 1 kg-m/s². In other words, a single Newton is equal lớn the force needed lớn accelerate one kilogram one meter per second squared.
