# When a falling skydiver finally opens her parachute of the drag force equals her weight what happens?

## When a falling skydiver finally opens her parachute of the drag force equals her weight what happens?

Eventually, the force of the resisting air balances out with the force of gravity, and the skydiver stops speeding up. Once she has reached this balance and is no longer accelerating, she has reached terminal velocity. Which is to say: drag is equal to weight, acceleration is zero, so velocity is constant.

## When a parachutist opens her parachute in what direction does she accelerate?

When a parachutist opens her parachute after reaching terminal speed, in what direction does she accelerate? When a parachutist opens her chute, she slows down. That means she accelerates upward. 93.

Why does a parachutist fall slowly to the ground when his or parachute opens?

As the skydiver gains speed, their weight stays the same but the air resistance increases. There is still a resultant force acting downwards, but this gradually decreases. When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.

How does a parachute change the skydiver’s terminal velocity?

As the skydiver gains speed, their weight stays the same but the air resistance increases. There is no resultant force and the skydiver reaches terminal velocity. When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.

### When a parachutist jumps from an airplane he eventually reaches a constant speed called the terminal speed once he has reached terminal speed?

When a parachutist jumps from an airplane, he eventually reaches a constant speed, called the terminal velocity. This means that: the force of air resistance is equal to the weight of the parachutist.

### Why does a parachutist stop accelerating downward after opening the chute and then falling some distance?

Air resistance is pushing up on the parachute and force of gravity is pulling down so she slows down. This increases friction which slows free fall down. So when the skydiver reaches terminal velocity, the force of gravity is balance by air resistance. But when the forces are balance, there is no acceleration.

How does the terminal speed of a parachutist before opening a parachute?

There are usually two terminal speeds, one before the parachute opens, which is faster, and one after, which is slower The difference has mainly to do with the different areas presented to the air in falling. The large area presented by the open chute results in a slower terminal speed, slow enough for a safe landing.

How are the forces change on a parachutist while they fall?

Newton’s Law says that the total (net) force on an object is proportional to it’s acceleration, so this force causes the parachutist to accelerate down. However, as they fall, the air starts to push back, so they experience a Drag force pushing them upwards trying to slow them down, which gets larger the faster they go.

## What happens to the velocity when a parachute is opened?

It gradually gets very close to equal to the downward gravitational force, leaving almost no net force and thus a new terminal velocity, which is now less than the one with the parachute closed. So although the acceleration is upwards, it never leads to an upward velocity, but just slows the downward velocity to a new, smaller value.

## Why does a man fall out of a parachute?

However as he slows down the upward force, in this case drag, produced by the chute falls, meaning it will eventually drop to a level where drag = gravity, and the man will fall at a constant rate. Therefore the man will never begin rising, unless there is some external force like an updraft or a gust of wind.

What does Newton’s third law say about opening a parachute?

Q & A: Opening Parachute. According to Newton’s third law, the parachutist will accelerate in the upwards direction. This does not mean he will move in the upwards direction. The parachutist is moving rapidly downwards before he opens the parachute, and acceleration upwards really is the same thing as deceleration downwards — he just slows down.
