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.
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.
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.
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.
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.
