What is the formula for force?

Answer 1

One formula for force is Newton's Second Law of Motion: Force = Mass * Acceleration or F = ma

On the earth's surface, F=mg

where

F= weight

m= mass

g= acceleration due to gravity

In fact, force is the rate of change of momentum and is given by:

F = dp/dt

where p is momentum.

F = dp/dt can be expanded to F = v(dm/dt) + m(dv/dt)

where m is mass, v is velocity.

F = m(dv/dt) = ma. This is for constant mass.

F = v(dm/dt) is used when velocity is constant but mass is changing.

Answer 2

Force = Mass x Acceleration
