Net force = Force of gravity - Force of air resistance = weight - air resistance = mg - 800N.
The net force on the parachutist is 300 N (800 N - 500 N = 300 N) in the opposite direction of the parachutist's downward motion. This net force contributes to the deceleration of the parachutist as they descend.
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
Air resistance, also known as drag, affects the way a parachutist falls by slowing down their descent. As the parachutist falls, the force of air resistance increases with speed, eventually reaching a point where it equals the force of gravity pulling the parachutist down. This creates a situation known as terminal velocity, where the parachutist falls at a constant speed without accelerating further.
It is air resistance which slows the rate at which a parachutist falls, turning what would otherwise be a fatal fall into a controlled landing.
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
The net force on the parachutist is 300 N (800 N - 500 N = 300 N) in the opposite direction of the parachutist's downward motion. This net force contributes to the deceleration of the parachutist as they descend.
If the falling parachutist has a downward force of 500 N, and the air resistance force is 900 N (negative), then the net force is:500 N - 900 N = -400 N So, the parachutist gets a net upward force, causing him to decelerate while continuing to move downward, due to gravity.
Air resistance or upthrust :)
'Drag' which is air resistance.
When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.

A parachutist has two terminal velocities because before the parachute is deployed, they fall at a faster velocity due to air resistance being lower. Once the parachute is deployed, the surface area increases, causing air resistance to increase and the parachutist to reach a new, slower terminal velocity.
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
Air resistance, also known as drag, is the force that slows down a parachutist as they fall through the air. The parachute helps increase the surface area, resulting in more drag force and slowing down the descent.
Air Resistance or friction with the air.
