Physics principles that can be observed in a theme park Introduction Physics is a vast topic that can be observed almost everywhere, even in a theme park, In a theme park physical principles such as 'weightlessness' and 'acceleration/deceleration' play an important role in ensuring that the rides are as exciting as they are safe. In this essay I will show how two certain physical principles are used in a ride to ensure that the ride is safe but at the same time gives a lot of excitement to the rider. I will explore the sense of 'weightlessness' during free fall and how 'forces' are used to ensure the ride is not dangerous. I will also mention how gravitational potential energy converts to kinetic energy as the ride falls. Physical Principles================ =============== Weightlessness Free fall is a term used to describe how an object moves through the air when there are virtually no forces other than gravity acting on it. During free fall, the object experiences a sense of "weightlessness", but weightlessness does not mean that an object loses all of its weight. Since in physics "weight" does not mean how heavy an object is (known as "mass"), "weight" is a term used to describe how much force and force the object exerts due to gravity, weight can only be felt if there is another force that opposes the direction of the weight, as stated by Newton's laws of motion that "all forces have a resisting force that is equal to and in the opposite direction of the force", on earth the resisting force is transmitted by the ground beneath our feet, so if the ground were to come away, as in free fall, there would be no resisting force and we would not feel the weight, this is what is meant by the term "absence of gravity". This is used in the ride I will study to create the sensation of falling into a pit and thus create a thrill. Stopping Forces Another physical principle I will explore is the use of forces
