In "Jurassic Park," Newton's First Law of Motion, which states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by a net external force, can be illustrated through several scenes.
One clear example is in the scene where the character Dr. Alan Grant experiences the inertia of a vehicle during the T. rex attack. When the vehicle stops suddenly, the characters inside are thrown forward due to their inertia – they were in motion with the vehicle, and when it comes to a stop, their bodies continue to move forward until restrained by seatbelts or another force. This vividly demonstrates how objects (or people) in motion continue to move in the same direction unless acted upon by an external force.
Additionally, the way the dinosaurs move in the film also showcases Newton's First Law. For instance, when a dinosaur runs or suddenly changes direction, it requires a force to act upon it to change its state of motion. The dramatic effects of inertia can be seen in various scenes, reinforcing the importance of this fundamental principle in physics.
