Study Notes

Big Dipper

Follows Newton's first law: remains stationary until an external force, such as the launch mechanism, initiates motion.
During descent, gravity accelerates the train down the slope; the train continues in motion due to inertia unless impacted by friction or air resistance.

Boomerang

Utilizes Newton's second law: acceleration depends on mass and applied force.
After reaching the top, gravity acts as an external force pulling the ride down, causing acceleration proportional to gravitational force and affected by the ride's mass.

Dodgem Cars

Illustrates Newton's third law: equal and opposite forces during collisions.
When dodgem cars collide, the force exerted by one car on another is equal in magnitude but opposite in direction, demonstrating equal experiences of force in different directions.

Car Safety Features

Designed to reduce collision impact on passengers, enhancing survival chances.
Understanding these features through Newton's Laws reveals their purpose and effectiveness.

Scalar and Vector Quantities

Scalar: Physical quantities with only magnitude (e.g., time, speed, volume, mass).
Vector: Quantities with both magnitude and direction, significant in motion studies (e.g., force, velocity, acceleration, weight, momentum, friction).

Formulas

Acceleration formula: (Final speed - Initial speed) / Time taken.
- Example: Velocity increases from 0 m/s to 5 m/s in 10 seconds results in an acceleration of 0.5 m/s².
Newton's second law formula: Force (N) = Mass (kg) x Acceleration (m/s²).

Speed and Velocity Triangles

Speed triangle: d = total distance, sav = average speed, t = total time.
- Example: Swimming 50 meters in 25 seconds results in an average speed of 2 m/s.
Velocity triangle: s = displacement, vav = average velocity, t = time.
- Example: A ball travels 6 meters in 3 seconds, resulting in an average velocity of 2 m/s.

Acceleration Triangle

∆v = change in velocity, a = average acceleration, ∆t = change in time.

Newton's Laws of Motion

First Law: Objects at rest remain at rest, and objects in motion maintain motion at constant speed unless acted upon by an unbalanced force.
Second Law: Acceleration of an object is dependent on its mass and applied force.
Third Law: Every action has an equal and opposite reaction.

Application of Newton's Laws in Rides at Luna Park

Seatbelts: Utilize Newton's first law by restraining passengers, preventing forward motion during sudden stops, which helps reduce injury risk.
Crumple Zones: Employ Newton's third law; the force from a collision is countered by a force from the wall. Crumple zones absorb impact, minimizing damage to the vehicle and protecting passengers.

Effectiveness of Safety Features

Seatbelts reduce fatal injury risk by approximately 45%.
Crumple zones ensure controlled deformation during collisions, safeguarding the passenger compartment and reducing injury severity.
