🤔 How it works …….. ⁉
Science behind the famous Circus stunt : The Globe of Death by motorbike or मौत का खुवा* ⁉ 🏍️
The Globe of Death is a circus and carnival stunt where stunt riders ride motorcycles inside a mesh sphere ball. It is similar to the wall of death.
The physics behind this trick is centripetal force. This is the force that acts on an object as it moves around in a circular path.
All forces have a direction in which they push, and centripetal force is directed towards the center of the circular path.
This feat is heavily based on timing between the riders to make sure they don’t crash into each other, but the reason they can ride around in circles and can ride upside down in the first place is a physics phenomenon centripetal force.
In other words, if you are driving your car🚗 in a circle, the centripetal force is directed towards the center of that circle. Centripetal force can be calculated using the following equation:
Fc = (m x v2) / r
Where:
Fc- is the centripetal force
m- is the mass of the object
v- is the velocity at which the object is moving
r- is the radius of the circular path
The moment the motorcycle and rider slows enough that they start to fall and lose contact with the top of the globe, the normal force immediately goes down to zero.
The motorcycle is not in contact with the globe, hence no force is being exerted on the globe, so the globe doesn’t have to exert anything back.
😳Why❓❓❓
Why can’t we see 🧐the details of an object far away?
Not being able to see objects in the distance is a condition called ‘ Myopia ’ and is commonly known as nearsightedness.
Causes of Nearsightedness Nearsightedness can also be caused by a cornea (clear layer at the front of the eye) that’s not shaped correctly. These two problems prevent light from focusing directly on the retina. Instead, light focuses in front of the retina, which makes distant objects appear blurry.
💁🏻♂️ GK TODAY
Westerners used to the Gregorian calendar, all mark the birth of Jesus Christ as year zero, and any year before that is denoted as BCE (before Common Era)
