A skydiver prepares to jump out of a plane. Explain how gravity and air resistance will affect the motion of the skydiver before and after he or she opens the parachute.
My response : Gravity will pull the skydiver down to the ground. As they're in the air and go accelerate faster, air resistance will increase. When the skydiver opens the parachute, air resistance will open the canopy and pull it up. Gravity will pull the skydiver down until the skydiver reaches the ground.
How is my response?
Thanks. :)
well, you ignored the air resistance during his forward motion (as he jumps out of the plane). It slows him.
Seriously, Celeste was being sweet. She basically said she doesn't know the answer, just like you don't. Stop picking on her cause she says babe and honey, ok? That being said, I think your answer, Carina, is pretty good.
Your response is generally accurate, but here's a more detailed explanation:
Before the skydiver opens the parachute, two main forces act upon the skydiver: gravity and air resistance. Gravity pulls the skydiver downward towards the ground, accelerating their descent. As the skydiver gains speed, the air resistance also increases.
Air resistance is a force that opposes the motion of the skydiver through the air. Initially, when the skydiver jumps out of the plane, the force of gravity is greater than the air resistance. This causes the skydiver to accelerate downwards, gaining speed as they fall. The force of air resistance also increases with the skydiver's speed.
When the skydiver opens the parachute, the dynamics change. The parachute increases the amount of surface area exposed to the air, creating a larger force of air resistance. This results in a significant increase in the overall force of air resistance acting on the skydiver.
After the parachute is deployed, the increased air resistance partially counteracts and balances the force of gravity. As a result, the skydiver experiences a reduced net force and decelerates. The parachute provides a large surface area, which slows down the skydiver's descent by creating drag. Eventually, the gravitational force and air resistance reach equilibrium, and the skydiver reaches a constant terminal velocity.
Therefore, your response is accurate in describing how gravity pulls the skydiver down before and after the parachute is opened, and how air resistance increases with the skydiver's velocity and plays a crucial role in slowing down the descent after the parachute is deployed.
