Modern parachute canopies are shaped like airplane wings and fly using lift rather than air resistance. Older parachute canopies are shaped like cones or jellyfish, and work purely by drag. The moving air inflates the canopy, which then slows the parachutist down as the force of the air pushing upwards on the bottom of the canopy exceeds the weight of the jumper. Eventually, the two forces are balanced and the parachutist descends at a slow and constant speed.

When a skydiver has reach the terminal speed what is the air resistance equal to what is the sky diver acceleration?
When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase indefinitely because of air resistance, which creates a "terminal velocity" where the force of air resistance balances the force of gravity. As the skydiver falls faster, air resistance increases until it matches the force of gravity, resulting in a constant speed.
If a skydiver jumps out of a plane which force is greater gravity or air resistance?
Initially, gravity is greater than air resistance, causing the skydiver to accelerate downwards. As the skydiver picks up speed, air resistance increases until it eventually balances out with gravity, leading to a constant speed called terminal velocity.
How can a skier achieve greater velocity than a skydiver?
If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.
Why does a skydiver loose speed when he opens his parachute?
A skydiver loses speed when he opens the parachute because the parachute creates drag by slowing down the movement of air. This drag force opposes the motion of the skydiver, causing a decrease in speed. Additionally, the larger surface area of the parachute increases the effect of air resistance on the skydiver's body.
Why is a skydiver's speed wont continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase because of air resistance, also known as drag force. As the skydiver falls, the force of air resistance increases until it balances out with the force of gravity pulling them downwards. This causes the skydiver to reach a terminal velocity, the maximum speed they can achieve while falling, before the parachute opens.
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
When a skydiver opens their parachute, air resistance increases which slows down the skydiver. Terminal velocity is the maximum speed a falling object can reach when the force of gravity is balanced by the force of air resistance. Opening the parachute decreases the skydiver's speed, allowing them to land safely.
What is an example of air resistance force?
An example of air resistance force is when a skydiver jumps out of a plane and experiences the force of air pushing against their body as they fall through the atmosphere. This force increases with the speed of the skydiver and can impact their descent speed and trajectory.
What is the overall net force of a skydiver?
The overall net force acting on a skydiver is the force of gravity minus air resistance. Initially, as the skydiver falls, gravity is the dominant force causing acceleration. As the skydiver gains speed, air resistance increases, eventually balancing out the force of gravity to reach a terminal velocity where the net force is zero.
What example of air resistance force?
An example of air resistance force is when a skydiver jumps out of a plane and experiences the force pushing against them as they fall through the air. This force acts in the opposite direction to the skydiver's motion and increases as their speed increases.
Is it true that the steady speed reached by a skydiver is called the terminal velocity?
Yes, that's correct. Terminal velocity is the constant speed that a falling object, like a skydiver, eventually reaches when the force of air resistance is equal to the force of gravity pulling the object downward. At this point, the skydiver no longer accelerates and falls at a constant speed.
Why is a skydiver not really in free fall?
A skydiver is not in true free fall because they are experiencing air resistance or drag as they fall through the atmosphere. This force opposes the motion and causes the skydiver to reach a terminal velocity, where the force of gravity is balanced by the drag force. This results in a constant downward speed rather than accelerating indefinitely.
