Starting a car with a dead battery illustrates how both the magnitude of force and the duration of force application are crucial. A sudden, short-lived push may not provide enough force to change the car’s momentum sufficiently, while a continuous push over time gradually increases the car’s momentum, eventually allowing it to reach the necessary speed to start the engine.

Starting a car with a dead battery relates to force and time duration in the context of the impulse needed to overcome static friction. A sudden, short-lived push may not provide enough impulse to overcome the initial resistance and start the engine due to the limited force applied over a brief time. In contrast, a continuous and sustained push over a longer duration gradually increases the impulse, effectively overcoming static friction and initiating motion in the engine components. This emphasizes the importance of both force and the time duration of its application in successfully starting a car with a dead battery.
