How does air resistance affect the way the parachutist falls?
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.
The speed an object reaches when the force of gravity is balanced by the force of air resistance?
Terminal velocity is the speed an object reaches when the force of gravity is balanced by the force of air resistance. At terminal velocity, the object no longer accelerates and falls at a constant speed. This speed varies depending on the mass, size, and shape of the object.
What is the graph of the motion of a body falling vertically that reaches a terminal speed?
The graph of the motion of a body falling vertically that reaches a terminal speed would show an initial acceleration until the body reaches its terminal velocity. At this point, the graph would level off, showing constant velocity as the body falls continuously.
How does the air resistance affect the parachutist's fall?
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.
What is the speed of a falling parachutist?
The speed of a falling parachutist is around 120 mph (193 km/h) when the parachute is fully deployed. This speed allows the parachutist to descend safely and land without harm.
When a parachutist is moving with a constant speed what happens?
There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity. The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!

What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?
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 an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
What will happen if a parachutist opens its parachute before reaching its terminal velocity?
During free fall, the parachutist reaches a terminal velocity (a constant velocity) of somewhere between 120 and 180 miles per hour. (If you go feet first, you go faster than if you lie on your back or front). When the parachute opens (hopefully), the terminal speed is reduced to around 12 miles/hour.
The speed an object reaches when the force of gravity is balanced by the force of air resistance is called what?
Terminal velocity.
What is the speed of an object that has reached terminal velocity?
The speed at terminal velocity depends on the mass and shape of the object. For example, a sheet of paper will have a very low terminal velocity; the terminal velocity for a man will be much higher.
