In what condition is the acceleration of a falling parachute is zero?

In summary, the acceleration of a falling parachute is zero when the forces of gravity and air resistance are balanced. Air resistance, also known as drag, increases as the speed of the parachute increases and eventually becomes equal to gravity, resulting in zero net force and zero acceleration. The mass and shape of the parachute can also affect its acceleration, with a heavier and larger parachute experiencing slower acceleration and a lighter and smaller parachute experiencing faster acceleration. However, the acceleration of a falling parachute is not always zero and can vary depending on the balance of forces acting on it.

What do you think?
 
  • #3


I think freefall
 
  • #4


When a jumper's parachute opens, he or she--hopefully--quickly reaches a terminal velocity. At that point, what is the net force on the parachute and its acceleration?
 
  • #5


Is it after reaching terminal velocity
 
  • #6


Still not clear

Give me clear answer on it.

Post #5 correct.Don't be tensed.
 

1. What is the condition for the acceleration of a falling parachute to be zero?

The acceleration of a falling parachute is zero when the forces acting on the parachute are balanced. This means that the force of gravity pulling the parachute down is equal to the force of air resistance pushing the parachute up.

2. How does air resistance affect the acceleration of a falling parachute?

Air resistance, also known as drag, is a force that acts in the opposite direction of an object's motion through air. In the case of a falling parachute, air resistance increases as the speed of the parachute increases. At a certain point, the force of air resistance becomes equal to the force of gravity, resulting in a net force of zero and zero acceleration.

3. Does the mass of the parachute affect its acceleration?

Yes, the mass of the parachute does affect its acceleration. The heavier the parachute, the more force of gravity it experiences. This means that a heavier parachute will need more air resistance to balance out the force of gravity, resulting in a higher terminal velocity (maximum speed) and a longer time to reach it.

4. Does the shape of the parachute affect its acceleration?

Yes, the shape of the parachute can affect its acceleration. A parachute with a larger surface area will experience more air resistance, resulting in a slower acceleration. On the other hand, a parachute with a smaller surface area will experience less air resistance, resulting in a faster acceleration.

5. Is the acceleration of a falling parachute always zero?

No, the acceleration of a falling parachute is not always zero. It is only zero when the forces acting on the parachute are balanced. If the force of gravity is greater than the force of air resistance, the parachute will experience a net downward force and accelerate towards the ground. If the force of air resistance is greater than the force of gravity, the parachute will experience a net upward force and accelerate away from the ground.
