If you are taking the variation of 'g' with altitude, then its weight is lesser, not greater, at the beginning of the descent. But for small heights, The variation of g is negligible, so its weight remains the same
Changing the weight of a parachute will affect its descent speed. A heavier parachute will fall faster while a lighter parachute will fall more slowly. This is because the weight influences the drag force acting on the parachute during descent.
The main forces acting on a parachute during descent are gravity, air resistance, and the weight of the parachute itself. Gravity pulls the parachute and its load downwards, while air resistance provides an upward force that slows the descent. The weight of the parachute adds to the overall force acting on the system.
The hypothesis for parachutes could be: "If the surface area of a parachute is increased, then the rate of descent will decrease because the air resistance will be greater, resulting in a slower fall."
To increase the hang time of a parachute, you can increase its surface area, which allows for greater drag and slower descent. Using a larger canopy or a specialized design, such as a winged parachute, can also enhance lift. Additionally, reducing the weight of the payload can improve hang time, as less weight means the parachute can stay deployed longer. Lastly, ensuring the parachute is deployed properly and at the right altitude can maximize its effectiveness.
Parachutes are interesting aircraft. The major retarding force of classical round parachutes is drag. Weight and drag determine their rate-of-descent. But air spills out of them because they oscillate, too. Since the 1960's parachutes have been designed that acheive lift from their forward motion.
Weight affects parachuetes because it brings it down faster. For example, a 180 pound guy and a 60 pound boy both take parachutes and sky dive. The man will reach the ground faster because he weighs more than the boy.
The fabric of a parachute significantly influences its hangtime due to its weight, porosity, and aerodynamics. Lighter fabrics allow for a slower descent and longer hangtime by reducing the overall weight of the parachute. Additionally, the porosity affects air resistance; less porous materials can create more lift and slower descent rates. Overall, the choice of fabric plays a crucial role in optimizing performance during freefall and descent.
The weight to material ratio for a parachute depends on various factors such as the size of the parachute, the weight of the payload, and the desired descent rate. In general, a common ratio is 5:1, meaning the parachute should be able to support 5 times the weight of the payload. However, it is best to consult a professional or refer to specific guidelines for more accurate recommendations.
A parachute's material affects the descent speed by influencing factors like drag and weight. Materials with higher air resistance and lower weight can slow down the descent speed more effectively than heavy or dense materials, resulting in a slower fall.
cross sectional area for air resistance is greater as you increase the parachute size.
A heavy weight will cause the parachute to fall at a faster rate than a light weight due to gravity's pull. The air resistance provided by the parachute will slow down the descent of both heavy and light weights.
A typical skydiver with an open parachute falls at a speed of about 15-20 miles per hour. The descent rate can vary depending on factors such as the size of the parachute, the weight of the individual, and wind conditions.
