Yes. Acceleration can be positive or negative. When he jumps out of the airplane and is in free fall, he is accelerating in a downward direction, so his acceleration is negative. When he opens his parachute, he accelerates in an upward direction, so his acceleration is positive.
What else can I help you with?
What are the effects of gravity on a falling parachute?
Gravity pulls the parachute downward, causing it to accelerate towards the ground. As the parachute falls, air resistance increases, slowing down its descent. This gradual decrease in speed allows for a controlled and safe landing.
What type of friction is a man falling out of an airplane in a parachute?
The man falling out of an airplane with a parachute is experiencing fluid friction, as the air molecules slow down the descent of the parachute due to air resistance.
Would a parachute be balanced when it falls?
As long as it is not accelerating (going faster and faster, or slower and slower), the forces on the parachute are balanced. Initially, the parachute will accelerate - in this case the forces are unbalanced. It will continue accelerating, until the force of gravitation is balanced by the force of resistance.
What is the name of the force which slows down a man falling with a parachute?
Air resistance, also known as drag, is the force that slows down a man falling with a parachute. As the parachute opens, it increases the surface area exposed to the air, creating more drag and slowing down the descent.
How does weight affect a parachute?
weight would affect a parachute if you put a 500lb man on a parachute and dropped him gravity would make him travel faster towards the ground compared to if you placed a 92lb boy on a parachute as the parachute applies the same force to both of them but the man weighs more so takes more to slow down and therefor lands down on the ground first By Alister Kelly
Will a man in a parachute when the air resistance is less than his weight accelerate?
Yes, until he reaches terminal velocity.
Who would fall faster a man with a small parachute or a man with a large parachute?
The man with a small parachute will fall faster.
What happens to a skydiver before they open their parachute?
They jump out of the plane and accelerate to terminal velocity.
Can you give me a sentence with the word parachute?

When you pull a cord on parachute do you go back up?
You do go up, relative to the cameraman, but you never actually gain altitude. When the parachute opens you accelerate upwards and you fell exactly the same as if you were accelerated upwards from rest.
Who invented the first parachute?
a man named somebody
When Simon goes to the mountain what does he discover?
the man in the parachute
Words used to describe the parachute man?
Ugh!
What is the name of the force acting on a man who is descending with a parachute?
"Gravity" is.
Can you put the word parachute in a sentence?
The man jumped out of a plane using a parachute so he would fall safely to the ground. We used a parachute so we could land safely on ground.
