How do parachutes slow something down?

Parachutes slow something down by increasing air resistance, which creates drag as the object falls through the air. The large surface area of the parachute catches the air, causing it to exert an upward force that counteracts gravity and reduces the speed of descent.


Does water affect how fast something falls?

Yes, however, even air affects how fast something falls. The weight of the water is what causes buoyancy (certain materials to float), and and the resistance of water plays a small role - the weight of the water being the larger role - in what causes other materials to fall slower than they would through air. There are actually certain things that are buoyant in the air, like helium. You will notice that if you let all the air out of your lungs, you will fall down through the water at a certain (very slow) speed. That speed is your terminal velocity through water. The terminal velocity of an average sized human through the air is about 55.6 m/s (200 kph or 124 mph). This speed is obviously much higher than the speed at which something falls through water. So water does affect haw fast something falls. "But wait, certain objects appear to fall through the water at the same speed that they fall through the air!" To explain this, water affects how fast something falls - compared to how fast it falls through the air - depending on its density. The object which you're talking about, is actually falling slower through the water, you just can't tell. We see this property in air too, why do you think a pound of feathers falls much slower than a lead weight?


What is the meaning of the potential energy formula?

The meaning is that, when you raise an object, due to its position it will have a kind of energy stored; this can be converted into other kinds of energy when it falls down. A practical example is water in a hydroelectric plant - when it falls down, electricity is generated.The meaning is that, when you raise an object, due to its position it will have a kind of energy stored; this can be converted into other kinds of energy when it falls down.

What is the name of the liquid that falls from the sky when it rains?

The liquid that falls from the sky when it rains is called rainwater. It is a natural form of precipitation that occurs when water vapor in the air condenses and falls back down to the ground.


What is meant when someone says that an object falls down?

When someone says that an object falls down, it means that the object is moving in the direction of gravity, typically from a higher position to a lower position without any external force supporting it.
