A diagram of a cylindrical vessel containing gas, with a movable piston held down by a weight. Countless small dots beneath the piston represent gas particles in rapid, random motion, illustrating Bernoulli's model of gas pressure. — physics As conceived by Daniel Bernoulli in *Hydrodynamica* (1738), gases consist of numerous particles in rapid random motion. He assumed that the pressure of a gas is produced by the direct impact of the particles on the walls of the container.

Newton’s second law is a fundamental principle in classical mechanics that quantifies the relationship between force, mass, and acceleration.12

The law states that the force $F$ acting on a body is equal to the product of the body's mass $m$ and the acceleration $a$ of its center of mass, expressed by the equation:

$F = m a$

In this relationship, the force is directly proportional to both the mass and the acceleration. This means that for a given mass, a greater force will result in a greater acceleration. Conversely, if the same force is applied to objects of different masses, the object with the greater mass will experience less acceleration, demonstrating the concept of inertia.123

Additionally, the law can be interpreted as stating that the rate of change of an object's momentum is equal to the strength of the applied force. This equation serves as the basic equation of motion in classical physics, allowing scientists to derive the velocity and position of an object over time if the acting forces are known.12
