What do parachutes do that cause skydiver to slow down?
simple air resistance
How does a skydiver float?
The momentum of the diver with the gravity against the thinner air in the altitude and the position of your body cause you to slow down your fall.
How does a skydiver us friction to slow down?
A skydiver can use friction by adjusting the position of their body to increase surface area and create more drag. By spreading out their limbs, the skydiver can encounter more air resistance, which helps to slow down their descent speed. This increase in friction allows the skydiver to control their rate of descent and eventually deploy their parachute safely.
When a skydiver jumps from a plane he is in a condition known as what?
Panic?Terror?Exhilaration?No, "FREE-FALL". Although one or more of the first three are likely, as well.By the way; a skydiver is only in freefall for about a second after the jump. After that, the air resistance of his body begins to slow him down until he reaches "terminal velocity".
Why do skydivers use parachutes scientifically speaking?
Skydivers use parachutes to slow down their freefall to a safe landing speed. The parachute creates drag, which counteracts the force of gravity pulling the skydiver towards the ground. This ultimately allows the skydiver to land safely without injury.
What shape what is the displacement versus time for the skydiver be?
The shape of the displacement versus time graph for a skydiver would be a curve that starts at zero displacement when the skydiver jumps out of the plane, increases as the skydiver falls accelerating due to gravity, and eventually levels off as the skydiver reaches terminal velocity. The curve will then be a straight line at a constant displacement representing the terminal velocity until the skydiver opens the parachute, at which point the displacement will decrease as the skydiver slows down and lands.
How does a skydiver change his or her speed?
Just as a leaf falls slower to the ground than a tennis ball, a skydiver changes his/ her body position to change the amount of surface area that is affected by air resistance. A flatter body position, for example, will slow a skydiver's freefall rate from a normal arched position.
What happens to the air resistance as the parachute opens?
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
Skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
80 m/s 2 up
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
Yes, if the acceleration of the skydiver decreases as falling progresses, it means the skydiver is slowing down. This indicates that the force of gravity pulling the skydiver downward is being countered by air resistance, causing the skydiver to decelerate.
When a skydiver opens their parachute they move upwards?
The skydiver doesn't move upwards when the parachute opens. In reality, the parachute creates air resistance, slowing down the skydiver's descent until they reach a safe landing speed. This process is what allows the skydiver to land safely.
A skydiver slows down from 65ms to 5ms by opening the parchute if this takes 0.75 seconds what is the skydiver's accerlation?
66.7 m/s2
