Impulse. Force and time

Mechanical momentum is a physical quantity that is defined as the product of the force acting on an object and the time during which the force acts. Mathematically, mechanical momentum is expressed as J = F ∆t, where J is the momentum, F is the force and ∆t is the time during which the force acts.

The mechanical impulse is a vector quantity, which means that it has a direction and a quantity. The direction of the mechanical impulse is the same as the direction of the force acting on the object. It has units of Newton-second (N-s) in the International System of Units (SI). It can also be expressed in units of kilogram-meter per second (kg-m/s) in the System of Technical Units (SUT).

The law of conservation of mechanical momentum states that, in an isolated system, the total amount of mechanical momentum before and after a collision is the same. This means that if two objects collide, the sum of their mechanical impulses before the collision is equal to the sum of their mechanical impulses after the collision.

Mechanical impulse is a very important quantity in physics, since it is related to many other physical quantities, such as velocity, amount of motion and kinetic energy.
