What is the formula for calculating impulse from force and time?

Impulse is defined as the change in momentum of an object, and it can also be understood in terms of the force applied to that object over a specific time duration. The formula that relates impulse to force and time is derived from Newton's second law and the definition of momentum.

The correct relation is given by the product of force and the time duration during which that force acts. Mathematically, this is represented as:

Impulse = Force × Time

This equation highlights that the total impulse experienced by an object is equal to the average force applied to it multiplied by the time duration for which that force is applied. This is particularly useful in understanding how forces can change an object's momentum over time.

Functionally, since impulse is also equal to the change in momentum (Impulse = ΔMomentum), the connection with force and time becomes evident in practical applications, such as calculating the effect of a collision or understanding how long a force must act to achieve a desired change in velocity.
