How is a parachute different from a hot air balloon?
Its a fairly large difference. A hot air balloon is meant for multiple people and it propels itself and maintains a high altitude by burning gas, making it float. A parachute is just meant for slowing someone's speed while falling
Why does smaller parachutes hit the ground before bigger parachutes?
If you have two parachutes, one big and one small, the biggest one will take more time then the other parachute. This happens because there is more room in the parachute which is causing air to go in side, which is air resistance. The smaller parachute has a lot of air resistance because it is smaller and there is less room for the air to go inside. However, the bigger balloon has little air resistance because it has more room in it for the air to get inside. The air is pushing the balloon up so it will fall slower.
What causes a parachute jumper to slow down?
A parachute is slowed down by air resistance.
Why does hot air balloons float?
To put it simply, hot air balloons rise due to heat produced by the burning of propane, the heat travels up through the balloon's valve into the balloon itself (the envelope) and up to the parachute valve. Since heat rises, the hot air balloon its self rises. Better answer: a boat floats on water because it weighs less than the water it replaces. likewise, a hot air balloon floats, because the weight of the total balloon + hot air is less then the volume of cold air it replaces. Air has a weight too, but normally you don't notice.
Why does a parachute keep you in the air?
It does not 'keep you in the air' a parachute slows down your rate of descent by traping air under the canopy.
What is the bottom of a parachute?
a person or on a hot air balloon, a basket
How does the shape of a hot air balloon affect it's flight?
The bigger the envelope\balloon is the slower you will go like a parachute
How much minute a man fall of an hot air balloon whithout a parrashoot?
*Parachute
Who was the artist that sketched a pyramid parachute 300 years before it was invented?
hot air balloon

Why does heat makes the parachute fly?
heat makes a parachute fly because when hot air goes into a balloon shape it blows up and then lifts into the air it acts like helium o yeahhhh
What is the parachute valve at the top of a hot air balloon is used for?
The valve allows hot air to escape, slowing the ascent of the balloon, or if the valve is left open long enough it will cause descent.
Can you make a parachute from a balloon?
Physically it is impossible. The air would rush through the bottom of the balloon so quickly that it would fill up fast and pop quickly.
How does a hot air balloon gain altitude?
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
Is the parachute an improvement over previous technology?
The idea of the parachute appears to go back to Leonardo Da Vinci, but human carrying ones were not made until the hot air balloon in the 1700s.

What objects use upthrust?
many things use upthrust, some i can name are: a hot-air-balloon, a aeroplane a parachute and possibly a elevator.
