Which formula describes Newton’s second law of motion?

The formula that describes Newton's second law of motion is F = ma.

Here's a step-by-step breakdown:

1. F stands for force, which is measured in Newtons (N).

2. m stands for mass, which is measured in kilograms (kg).

3. a stands for acceleration, which is measured in meters per second squared (m/s²).

So, according to Newton's second law of motion, the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). This means that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
