An impulse is a force applied to an object that causes it to exert a force on another object, leading to a change in motion or an increase in the object's internal energy. In simpler terms, it's the instantaneous change in momentum of an object caused by an applied force.
Examples:
When you push a heavy box, the force you apply to the box causes it to exert a force on you, resulting in an increase in your momentum and ultimately, the box moving away from you.
When a car is accelerating, it experiences a force pushing it forward, causing the car to accelerate and increasing its momentum.
When water flows through a turbine, the flow of water creates a pressure difference, generating a force that pushes the turbine blades and generates power.
Impulse is an important concept in thermodynamics because it helps explain the relationship between applied forces and the resulting changes in motion and energy of objects. By understanding impulse, we can analyze the efficiency of thermodynamic systems and design machines that efficiently convert energy from one form to another
