How Does A Helicopter Work: Everything You Need To Know About Helicopters
A helicopter works on the principle of aerodynamic lift - an upwards force that opposes the weight of the helicopter and holds it the air. So how exactly do the rotors of helicopters help them fly? For any object to fly in the air, it...

Could We Dissipate A Tornado By Firing A Rocket Into It?
A tornado forms when there is a hot layer of atmospheric air that is covered by a relatively cold, dry bank of air above. When the warm air at the bottom of the atmosphere rises (due to its temperature), it pushes up on the cold air...

Why Is Static Friction Greater Than Kinetic Friction?
Friction is the resistance that one object or surface experiences when moving over another object or surface. The two types of friction that come into play when moving two objects against one another are static and kinetic. Static...

Why Don't We Colonize The Moon Instead Of Mars?
The Moon's proximity to Earth and geological similarity make it an enticing target for colonization. At just three days away, communication delays would be mere seconds. Its surface may also contain frozen water and oxygen extracted from...

Why Do Tightrope Walkers Carry Long Poles when Walking on A Rope?
Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

Archimedes Principle: Explained in Really Simple Words
Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes...
