What's the difference between impulse and momentum ?
When do we use impulse or when do we say a body has impulse ?

jtbell said:Impulse is to momentum as work is to kinetic energy.
Work-energy theorem: ΔK = W (the change in an object's kinetic energy equals the work done on it)
Impulse-momentum theorem: Δp = I (the change in an object's momentum equals the impulse acting on it)
Impulse and momentum are both physical quantities that describe the motion of an object. However, they have different definitions and units. Impulse is the product of force and time, while momentum is the product of mass and velocity.
Impulse and momentum are closely related, as impulse is defined as the change in momentum of an object. In other words, impulse is the force applied to an object over a certain amount of time, resulting in a change in the object's momentum.
It depends on the context. In situations where time is a critical factor, impulse may be more important as it determines the change in momentum. However, in cases where the mass and velocity of an object are significant, momentum may be more important.
Yes, both impulse and momentum can be conserved in a closed system where there is no external force acting on the system. This is known as the law of conservation of momentum.
Impulse and momentum are important concepts in physics and are used in various real-world applications such as rocket propulsion, car safety systems, and sports. They are also essential in understanding collisions and the transfer of energy in different systems.
