Question : "Impulse" can be defined as:
Option 1: the force acting on a body for a very long time.
Option 2: the work done by a body for a short time.
Option 3: the force acting on a body for a short time.
Option 4: the temperature acting on a body for a short time.
Correct Answer: the force acting on a body for a short time.
Solution : The correct option is the force acting on a body for a short time .
Impulse is the product of force and the time over which it acts on a body. Mathematically, it is expressed as impulse = force × time. It signifies the change in momentum, providing insights into how force influences an object's motion, particularly during brief interactions.
