What is the overall net force of a skydiver?
The overall net force acting on a skydiver is the force of gravity minus air resistance. Initially, as the skydiver falls, gravity is the dominant force causing acceleration. As the skydiver gains speed, air resistance increases, eventually balancing out the force of gravity to reach a terminal velocity where the net force is zero.
Are the forces balanced or unbalanced when a skydiver is accelerating downward?
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
When a skydiver jumps out of a hovering helicopter so there is forward velocity. what is the skydiver's acceleration?
Initially, the skydiver will experience an acceleration due to gravity, which is approximately 9.81 m/s^2 downward. As the skydiver falls, air resistance will oppose this acceleration, causing the skydiver to reach a terminal velocity where the downward acceleration due to gravity is balanced by the upward force of air resistance.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.

What are the forces acting on a skydiver?
The main forces acting on a skydiver are gravity, which pulls the skydiver downward, and air resistance (drag), which acts in the opposite direction of motion. As the skydiver falls, air resistance increases until it balances out the force of gravity, leading to a constant velocity known as terminal velocity.
What force changes when a sky diver opens his parachute?
When a skydiver opens his parachute, air resistance (also known as drag force) increases. This is due to the parachute creating a larger surface area and creating more resistance against the air, which slows down the skydiver's fall. This increased air resistance counterbalances the force of gravity acting on the skydiver.
what force is increased after the skydiver open parachute?
To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.
When air resistance is greater than force of gravity what will be the effect of force?
When air resistance is greater than the force of gravity acting on an object, it will slow down the object's descent. This is because the air resistance force counteracts the force of gravity, reducing the acceleration of the object as it falls.
When a skydiver has reach the terminal speed what is the air resistance equal to what is the sky diver acceleration?
When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.
Why is a skydiver's speed wont continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase because of air resistance, also known as drag force. As the skydiver falls, the force of air resistance increases until it balances out with the force of gravity pulling them downwards. This causes the skydiver to reach a terminal velocity, the maximum speed they can achieve while falling, before the parachute opens.
