Question

what do we mean f=ma

Answer 1

Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration

Answer 2

F=ma

Here,
F is force
M is mass
and A is acceleration

therefore, F=ma means Force is always equal to the product of mass and acceleration.
This is Newton's Second law of motion.

& Force is directly proportional to mass and acceleration.
