Final answer:
Increasing the time during which a constant force is applied to an object will result in a larger change in momentum, therefore a larger impulse.
Step-by-step explanation:
The impulse given to an object is directly proportional to the time during which a constant force is applied to it. Increasing the time interval over which the force is applied will result in a larger change in momentum, therefore a larger impulse. This can be understood by considering the equation for impulse, which is given by the product of force and time: Impulse = Force × Time.
