When bodies are accelerated, i.e., when the magnitude or the direction of their velocity changes, it is
necessary to use
Newton’s first law
Newton’s second law
Newton’s third law
Newton’s second law can be stated as follows:
If the resultant force acting on a particle is not zero, the particle will have an acceleration
proportional to the magnitude of the resultant and in the direction of this resultant force.
If the resultant force acting on a particle is equal to zero, the particle will have an acceleration
proportional to the magnitude of the resultant and in the direction of this resultant force.
If the resultant force acting on a particle is not zero, the particle will have an acceleration
proportional to the moment of the resultant and in the direction of this resultant force.
If the resultant force acting on a particle is equal to zero, the particle will have an acceleration
proportional to the moment of the resultant and in the direction of this resultant force.
The constant value obtained for the ratio of the magnitudes of the forces and
accelerations is a characteristic of the particle under consideration; it is the * of the
particles and is denoted by m.

The vector mv is called the *, or simply the momentum, of the
particle. It has the same direction as the velocity of the particle, and its magnitude is equal to
the product of the mass m and the speed v of the particle
