Final answer:
The situation demonstrating the law of acceleration is a passenger moving forward when a jeepney stops suddenly, exemplifying Newton's second law of motion, which equates force to mass times acceleration (F = ma).
Step-by-step explanation:
The situation that demonstrates the law of acceleration is D. A Passenger Tends To Move Forward When The Jeepney Suddenly Stops. This scenario illustrates Newton's second law of motion, which states that acceleration is proportional to the force applied to a mass. When the jeepney stops abruptly, the passenger's body continues to move forward due to inertia until an external force, such as the seatbelt, applies a stopping force. The passenger's body tends to accelerate forward because no force was applied to counteract the jeepney's stopping motion immediately.
Newton's second law can be mathematically expressed as F = ma, where F is the force applied to an object, m is the mass of the object, and a is the acceleration. This law is essential when trying to understand why objects accelerate the way they do and is fundamental to solving problems in dynamics. For instance, knowing the mass of the passenger and the force of the seatbelt can allow us to calculate the passenger's acceleration during the abrupt halt.
