Momentum and impulse are important concepts in physics that describe the motion of an object.
Momentum is a vector quantity that is defined as the product of an object's mass and velocity. It can also be thought of as the "quantity of motion" an object possesses. The momentum of an object is given by the equation:
Momentum = mass × velocity
The unit of momentum is kilogram-meter per second (kg·m/s). Since momentum is a vector, it has both magnitude and direction. It is important to note that momentum is conserved in a closed system, meaning that the total momentum before an event or collision is equal to the total momentum after the event or collision.
Impulse is a change in momentum and is defined as the product of the force applied to an object and the time interval over which the force is applied. Impulse is given by the equation:
Impulse = force × time
The unit of impulse is Newton-second (N·s) or kilogram-meter per second (kg·m/s). Impulse is also a vector quantity and has both magnitude and direction.
The relationship between impulse and momentum is described by the principle of impulse-momentum. According to this principle, the impulse exerted on an object is equal to the change in its momentum. Mathematically, impulse can be expressed as the integral of force with respect to time. This principle is often used to analyze the motion of objects during collisions, where the change in momentum can be determined based on the impulse exerted during the collision.
