How do bumper cars at an amusement park demonstrate Newtons third law?
Bumper cars at an amusement park demonstrate Newton's third law of motion, which states that "for every action, there is an equal and opposite reaction."
When two bumper cars collide, the force exerted by one car on the other is matched by an equal and opposite force exerted by the second car on the first. The action force is the force with which the first car hits the second car, while the reaction force is the force with which the second car hits the first car.
This is possible due to the principle of conservation of momentum. Momentum is the product of an object's mass and velocity. When the two cars collide, they experience an exchange of momentum. The action force causes the first car to lose momentum while the second car gains momentum, and the reaction force causes the second car to lose momentum while the first car gains momentum. Thus, the total momentum of the system remains constant.
These equal and opposite forces and the exchange of momentum causes the cars to move away from each other after collision. This is why bumper cars bounce off each other rather than sticking together upon impact.
Overall, the interaction between the bumper cars follows Newton's third law by showcasing the equal and opposite forces experienced by two objects colliding, demonstrating the law of action and reaction.
