Newton's Second Law
While Newton's first law looks at how force affects the motion of objects, the second law dives into how we define force itself. Newton's second law states that an object's acceleration (or a) is directly proportional to the net force (or F) acting on it and inversely proportional to its mass (or m). Unlike Newton's first law, there is no shorthand name for this one, but it is better known by its mathematical formula, which you can see:
However, it is far more common to see it written in the form where it has an equal sign instead of a proportional sign, which you can see:
This formula tells us that a force acting upon an object is equal to that object's mass multiplied by the acceleration caused by the force. You'll find this formula consistently used throughout your studies of introductory physics.
One excellent example of Newton's second law at work in our lives is our weight. You might not usually think about it this way, but your weight is actually the gravitational force of the earth acting on you. Your weight is equal to your mass multiplied by the acceleration due to gravity, 9.81 m/s.
